Successful October: In-house trade fair

More than 600 customers and enthusiasts came to KNOLL's in-house trade fair from 20th to 22nd October. The response was overwhelming, serving as confirmation of the incredible progress we have made in the past few years in our efforts to develop a world-class production system.


The three main subjects which were the focus of the fair – the ControLube minimum quantity lubrication system, the MicroPur® ultra-fine filter and the TS assembly and transport system – were successful in drawing in the public. The customers felt very at home at the in-house trade fair. After specialist lectures and an extensive tour of the site, our catering service ensured that visitors were well fed.


An information evening was reserved for representatives of the town of Bad Saulgau. Retired former KNOLL employees visited us the following evening.

The MicroPur® ultra-fine filter features an enormous range: From standardised systems for single machines or multiple machines to individual, central filter systems for entire manufacturing divisions. The two-stage system with a compact bandpass filter and a continuous loop also provides an economical alternative to classic pre-coated filtration.

The TS system attracted completely new industries. It demonstrates effectiveness and versatility in assembly, transportation and logistics.

The new technology of the ControLube minimum quantity lubrication system was the main point of interest for all visitors. It was evident in this case too that our efforts in developing this system paid off, producing a convincing result.


14 days in the limelight: trade show appearances for MX and TS

For the second time, the MX was presented to a broad audience, from small bakery operations to large industry, at the IBA Munich (September 12-17). At almost the same time, it was also presented at the Process Expo in Chicago (September 15-18). The focus was on the service-friendliness of the pump and its variants thanks to the toolbox system. KNOLL will show the TS transport system at Motek in Stuttgart (October 5-8). Here we will show conclusively that the TS offers effective solutions for the assembly and logistics industries.


Happy with the transport system for 365 days

A renowned Upper Bavarian partner company in the vehicle industry, which specializes in the processing of sheet metal and pipes, has been profiting from KNOLL's sophisticated TS-S/TS-G transport system for truck cross member assembly since fall 2014. The company was able to reduce the space required for truck cross member assembly by approximately one-quarter. The time required was reduced by approximately 50 percent. In addition to the conversion to line production, the integrated process control technology provided by KNOLL made a significant contribution to this. The Upper Bavarian company got to know the KNOLL transport system at Motek in 2012. After a benchmark with other suppliers, KNOLL emerged as the clear winner. Decisive for the customer were the modular construction and expandability of the KNOLL system, as well as the fact that at KNOLL, everything comes from a single source.


41 trainees start their training

Never before was the number of new trainees at KNOLL as high as in 2015. 41 trainees, and thus approximately 10% more than in the previous year, began their training. New this year are two professional fields: a combination course of study as Industrial Mechanic with Bachelor's degree in Industrial Engineering (at Albstadt-Sigmaringen University), and Construction Mechanic with similar orientation as the Industrial Mechanic, but with focal points in sheet metal working/welding. All trainees are introduced in the respective departments, where they will be well-integrated. Managing Director Jürgen Knoll: "For example, our trainees are granted access to everyday operations from the very beginning thanks to project work. According to the state of their training, individual responsibility is increased consistently in the course of their training." In the first week of training, after an introduction by Managing Directors Matthias and Jürgen Knoll, the new trainees enjoyed an outdoor "get-to-know-you day" on the Danube for team building. All trainees participated enthusiastically in the event in Sigmaringen and were able to gain some initial experience for their training period as a team: "When people help and support each other, they can do almost anything – even master situations that initially look very difficult," says trainer Peter Widmann. KNOLL currently employs 110 trainees and more than 900 other people.


TSS transport system

A renowned manufacturer of industrial trucks is relying on the KNOLL TSS transport system for the assembly of lift truck cabins. For a production plant in the Czech Republic, KNOLL planned the assembly line to order. Planned completion is October 2015. The system has 5 workstations with a total assembly time of 125 min. The transport speed is 0.2 m/min, during which the employees assemble the transport cabins on the conveyor belt, which runs continuously. For company-internal transport, the assembly carriages are used with tugger trains. Especially well-received was that KNOLL was able to present a solution that requires no assembly and product adjustments by the customer.

He was born in 1971 and studied mechanical engineering, with a focus on design and development, at the Fachhochschule Augsburg (Dipl.-Ing. FH). His previous jobs took him from a gear manufacturer to a pump producer, where he gained a lot of experience in the pump sector, to KNOLL.


KNOLL Gesund: New courses are coming.

The varied program KNOLL Gesund is also planning interesting things for the coming months. These include a vegan cooking course not just for vegans, but also for employees who want to learn more about vegan nutrition and alternative foods...a paddle-team day in the Upper Danube Valley... a lecture about nutrition in shift work by Sven Bach, known as the nutrition expert from the TV show "Kaffee und Tee" on SWR...the expansion of medical care offerings, for example an intestinal cancer prevention campaign. As soon as more details about these actions are available, a flyer will inform you about payment through payroll and the actual dates. In April, the Nordic Walking group started again. Additional participants are always welcome here! The group walks the whole summer through, always on Mondays.


Pioneering project: the young ones are coming.

Students in the 4th grade at the Lilly-Jordans-Schule in Herbertingen made initial contact with KNOLL. Embedded in a project in the form of a game called Tic Tac Toe, KNOLL explained technology to the kids and they got to know a bit about KNOLL's training program as well as components such as metal processing and electrical equipment in playful fashion. The feedback from the school was very positive. "Among the teachers and especially the students and parents, we left a very positive impression and clearly we were discussion topic number one," rejoices training coordinator Dirk Reiner. KNOLL will offer this project once a year at the Herbertingen school and thus reach out to both trainers and trainees. And the project should also be introduced at the Berta-Hummel-Schule in Bad Saulgau. With this initiative, KNOLL is a pioneer in the region, and it can prove once again that training is among the most important building blocks for KNOLL.



Strong together: KNOLL scores points with Engineering

Colorful and sweet: the MX at ProSweets in Cologne

Whether sweet or sour, the MX progressing cavity pump from KNOLL pumps everything, from chemical substances to paints and colors, to pharmaceutical products, on through to sweets. KNOLL exhibited the MX at ProSweets in Cologne from February 1-4. For this, a special trade show model was developed: the MX tower. Like a variable sales booth, it offers the opportunity to turn the individual components of the MX. This way, it is possible to combine the various options easily, simply by turning the components. This makes clear the modular toolbox system of the MX. The combination possibilities can be explained effectively and clearly. The concept was well-received by visitors to the largest international supplier trade show for the confectionary industry.


Well-filtered and awarded the prize: advertisement of the month

The concept behind the KNOLL advertising motif of the year for 2014 was the purity law. The MicroPur® superfine filter passed the comparison with Germans' favorite beverage effortlessly and won the prize for the advertisement of the month in September 2014 in the Industrieanzeiger. The jury praised the impressive picture and the claim. "It became clear in this process that the concern is purity in a demanding situation and that this claim is being made for KNOLL systems."






Broad-based investment – education partnerships

Meanwhile, KNOLL has formed educational partnerships with the Werkreal- and Realschule, as well as with the Störck-Gymnasium Bad Saulgau, the Realschule Mengen, and the Leopoldschule in Altshausen. In the course of the partnerships, projects in technology classes explain the topic of technology (metalworking and electrotechnology) to students. School events inform about training possibilities and KNOLL participates in professional days at the Realschule in Bad Saulgau and Mengen. Here, the following questions are answered: Does this profession suit my inclinations and capabilities? Do my prerequisites fulfil the requirements of the desired profession? Students profit from this tie to reality. Just as important to KNOLL is the presentation at educational events. Thus in February, there was another KNOLL booth at the "Marktplatz Ausbildung" in the Bad Saulgau Berufsschulzentrum.

Heat-resistant conveying for cooling down plastic moulds

KNOLL supplies a heat-resistant assembly and conveying system for a manufacturer of highly wear-resistant special plastics. The workpiece carriers are loaded automatically with the plastic moulds at a transfer station. The workpiece remain in the cooling section until the specified temperature has been reached. They are then released for discharge and requested by the push of a button. Without additional aids, the workpieces then leave the conveyor belt via exit ramps.

System with ERP connection for manufacturing cross member units for lorry undercarriages

For a supplier who rivets sheet metal assemblies in the heavy goods vehicle industry, KNOLL designed an assembly and conveying system with ERP connection. The plant is used for the manufacture of cross member units for lorry undercarriages. The system uses 14 carrier plates that constantly remain on the conveying system. Assembly points are installed by the customer on the carrier plates. Each carrier plate is assigned a job via an identification system. All information required is called up at all workplaces (loading station, riveting station, measuring station, removal station) by means of a process control system.

KNOLL knows exactly what customers in Switzerland want: precision and tidiness

25 machining centres, volume flow 2,000 l/min, brass machining


For a Swiss luxury watch manufacturer, KNOLL configured and set up the central system technology and provided process support. The trust placed on KNOLL by the company is based on experience: already in 2010, KNOLL supplied a central system. Absolute process reliability was also essential in the present case and, due to the special product, very high requirements regarding system cleanness had to be met. The project also included planning of the hall pipework, including the option for switching over from the second to the first system.

KNOLL progressing cavity pump MX

One of KNOLL's strengths is to find solutions that ensure trouble-free machining processes at the customer's and which are also future-oriented. This applies to all product areas of KNOLL and for areas that are served. Here, you can see successful applications of the progressing cavity pump MX with customised solutions for the food supplies and painting industry. The MX also works successfully in the sectors chemicals, pharmaceuticals and cosmetics. 


"Decisive factors for Hänsel were, for example, the hygienic design of the MX and the superior cleaning capacity."

Hänsel Processing GmbH is a well-known plant and system provider in the sweets industry. It has already been using the MX progressing cavity pump for many years with great conviction. Its heatable double jacket made of high-grade steel, allows media, such as toffee, fudge or jelly masses, to be kept at a constant temperature and to be conveyed in a gentle manner. 


"IsernHäger decided to collaborate with KNOLL because we supply the MX progressing cavity pump not only in a standard version but can also configure it to customer specifications."

IsernHäger, pioneer in machine-controlled systems for starter and sour doughs, is a supplier of precision system technology. For customers from the bakery industry, IsernHäger developed a complete plant. A special version of the progressing cavity pump MX30R is used for mixing and pumping the starter dough. The progressing cavity pump received a suction housing with a relatively large diameter, the cleaning connections were equipped with nozzles for feeding fresh water.  


"For conveying the chocolate mass in the temperature control circuit, we replaced the previous positive displacement pump by a KNOLL progressing cavity pump MX30S. The prerequisite for a very stable crystallisation process was thus created." 

Uniform pressure and throughput combined with a small design, hygienic structure and heatable – this is what the responsible staff at Ritter Sport appreciated most of all about the KNOLL MX progressing cavity pumps. The chocolate manufacturer uses these pumps at various points: for conveying filling with high fat content independently of pressure into the aeration machine and for conveying constant masses of the chocolate into the tempering machine.


"We have already been using the MX progressing cavity pump from KNOLL for two years and can gladly confirm its excellent performance data and its high chemical resistance."

FreiLacke required an elastomer-free progressing cavity pump. KNOLL modified the vertical submerged pump MX20T and developed a joint-free version with a solid material stator made of PTFE. The plastic is chemically resistant, reacts very slowly, can be used at temperatures of up to 260 °C and resists the frequent use of aggressive cleaning agents.

The 37 new trainees from KNOLL were photographed in the new sheet metal processing hall. The family enterprise, with a total workforce of almost 900, currently employs 111 trainees. A new feature this year is the recognised occupational training course industrial electrician in production engineering. Trainees at KNOLL are integrated in the company processes because they are being trained to meet our own future personnel requirements. This is why, together with all employees, they are particularly pleased with the KNOLL Talent Pool, a program in which you can apply for special further training and qualification options. 


Thank you for your loyalty.

We wish all the best to Karl-Anton Menner, Wolfgang Schirmer and Norbert Walter, who are retiring this year. Harald Bleicher, Bernhard Boscher, Peter Engler, Claudia Heimpel, Ugur Kazanbas, Armin Menner, Wolfgang Neuburger, Metin Öreten, Peter Rimmele, Roland Rist and Reinhard Wehner celebrate their 25-year KNOLL anniversary this year. Thanks very much all of you for your trust, commitment and long-standing co-operation with KNOLL. For all building measures, KNOLL always focuses on tidy and bright working environment for production and administration. A generously proportioned glass façade, plenty of daylight and an unobstructed view of the lovely natural landscape is also available in the new hall for sheet metal processing, where the staff celebrating an anniversary and the retirees were photographed. 




KNOLL is also on board: Inclusion in Upper Swabia

Inclusion paraphrases the demand for equal rights of participation in society. All persons should have opportunity to fully participate in an equal manner in all social processes. INIOS – Inclusion in Upper Swabia is an initiative that meets this demand for inclusion. Members of a company are given the opportunity to work in a workshop for people with disabilities. In return, the member of the workshop accompanies the exchange candidate to his/her own company. KNOLL has been participating in the scheme since this spring and, since September, has allowed all trainees in the company to take part. The co-operation takes place with the "Oberschwäbischen Werkstätten (OWB)" in Mengen and Bad Saulgau. Managing Director Matthias Knoll is convinced by the INIOS concept: "Social competence is highly significant in our company. This form of exchange offers excellent opportunities to gain practical experience in this field." KNOLL instructor Peter Widmann has already made a positive intermediate assessment: "We learn the importance of the readiness to help others, openness and acceptance of fellow human beings who are different."


Perfect Partners: KF-E and MicroPur®

The combination pays off: compact belt filter with KF-E endless belt and the MicroPur® superfine filter are suitable especially for great chip loads or a high number of particles that can be backflushed only with difficulty. KNOLL supplied precisely this system technology to an owner-operated company in southwest Baden-Württemberg. This manufacturer of highly-precise steel parts such as pump pistons, hydraulic feeders, and ground axles and shafts works for the automobile industry as well as for manufacturers of high-pressure cleaning devices and electric motors. Won over by KNOLL, the company examined a reference system. The system scores with a series of advantages. It is especially maintenance-friendly, the filter elements can be changed during ongoing operation. Frequency-controlled filter pumps ensure tailored filtration. Filter modules and compact belt filters can be switched on or off as needed. An innovative control concept guarantees high temperature stability. The reclaimed oil is fed back into the system. The setup is very compact and space-saving.


System technology

  • Initial separation thanks to 5 KF 600 compact filters
  • 4 MicroPur® 480F filter modules
  • AK 30 automatic concentrator
  • 180 kW plate heat exchanger
  • Central group conveyor
  • Chip press


System configuration

  • Material: Steel
  • Working process: Grinding
  • Machines: approx. 10
  • Volumetric flow: 1,500 l/min
  • Cooling lubricant: oil

  • Nominal degree of filtration: 3 - 5 µm




Presented at Motek: the transport system holds up under as much as 5000 kg/m

For the second time, KNOLL presented the assembly and transport system at the international trade show Motek in Stuttgart. This trade show held each year in October is the industry platform for automation. Ideal for KNOLL for presenting its flexible, modularly-structured logistics system. Interest and resonance were very positive – more than 100 promising contacts were obtained, and the enhancement of components met with particular approval in all industries: whether automobile, mechanical engineering, chipping, robotics, furniture, white goods or the consumer goods industry. This assembly and transport system can do a lot. Meanwhile there is a version as a belt system (TSG). Its core element is a straight-linked chain that can move up to 5000 kg/m. This version is suited for simple logistics tasks and as an optimal complement to assembly applications. It offers the advantage that it can also transport pallets, grid boxes, and customer-specific carrier plates. Due to its great rigidity, the assembly and transport system in the TSS version with accumulating rollers (TSS) is perfectly suited for medium-heavy and heavy assemblies and workpieces. It manages loads up to 1500 kg/m. New from KNOLL is also the model with underfloor chain (TSZ) which provides a barrier-free assembly and logistics solution. With this system, the modular transport carriages, which can be combined with traverses to form larger units, are hooked into the jerk chain and can then be moved themselves across long distances. The synchronization of several chains allows the safe timing of the units. This is especially useful for areas where bulky and heavy assemblies must be moved.





Team building provides energy and power

This year's get-to-know-you day for new trainees at KNOLL featured an outdoor training in Sigmaringen. On the program for the 37 new trainees and their four trainers was "team building." The result in the evening was a freshly-formed WhatsApp group of all trainees in the various KNOLL departments in order to maintain contact and assist one other during the upcoming training period. The path there led across the Hornstein ruins, along the Lauchert with GPS devices, to a stream crossing on a rope 20 mm above the water, crawling through a cave, and other adventurous activities. Do people overcome obstacles better together and with communication or by working against each other? The answer to this question was clearly that teams that communicate well get further. "The day was worthwhile in any case and we learned and laughed a lot together," was the conclusion of trainer Peter Widmann.



KNOLL employees donate hours for flood victims

KNOLL employee Mujo Mehinovic is Bosnian; his homeland was especially hard hit by the flood catastrophe in the Balkans this spring. He was able to get a sense of the scope of the problem on-site and he really wanted to help. Therefore, he and his supervisor inspired the creation of an aid action at KNOLL. Managing Director Matthias Knoll approved the idea, as did many KNOLL employees. Thanks to a wave of helpfulness, the hours donated amounted to EUR 21,000. The management more than doubled the amount, to EUR 50,000, and also provided a used Vito company car and numerous corporate giveaways as donations. The idea behind the donation was that the donations should arrived precisely where they are needed. Therefore, Mujo Mehinovic has already driven to Bosnia three times this year on vacation. There he purchased food, put together aid packages, and distributed them directly on-site. He carefully selected the people who needed money the most. For example, a home for disabled people where the windows and doors were completely destroyed by the flood received financial assistance, as did a home for elderly people, single people, and displaced people, as well as two destroyed playgrounds that needed to be rebuilt. However, negotiations with the authorities in the Balkans are more complicated than the KNOLL employee had imagined. "This is precisely why it is so important to hand over the donations personally. In order to keep an eye on how they are used. This is tiresome, but the children's smiles make it worthwhile and give me the strength to keep helping," he says. Meanwhile, EUR 36,000 has been distributed; by the end of the year, another EUR 14,000 will be donated to particular projects, especially to families that are at a social disadvantage.


KNOLL gives customers energy-efficient systems

At AMB in Stuttgart, from September 16-20 in Hall 6, Booth C38, KNOLL will demonstrates its special expertise in the conveyor, filter, and pump product sectors. The focus of all the company's products is energy efficiency, sustainability, and space savings. The latest model of the MicroPur®, the F series, will be presented for the first time. Its ideal area of application is metal carbide and HSS tool grinding, as well as honing and lapping. Allowing you to achieve a degree of filtration of less than 3 μm, it is able to separate out incredibly small impurities from oil. Additional advantages of the new F series include the reversible flow technology, which is even more effective than before, extending the service life of the filter cartridges and reducing maintenance costs. The VLO vacuum filter is aimed at the manufacturers of gear hobbing machines. It reveals its special efficiency when grinding beneath oil. With the new design, up to three filter modules, each with a flow rate of 300 l/min, can be stacked one on top of the other. Pumps fitted with frequency controllers, along with the associated valve technology, play an important role, providing precisely the required level of filtration in order to save energy. It is often even worthwhile to retrofit existing systems. We have developed the E-PASS in order to test them with an efficiency analysis. Bridging the gap between KNOLL pumps and conveyors are what are known as shredder pumps. These centrifugal pumps are able to shred long chips, predominantly of aluminum, to pump-appropriate size and then to pump them with the cooling lubricant into the central preparation station.

KNOLL OPEN provides an opportunity to see world-class tennis

The KNOLL OPEN was held from July 28 to August 3 in Bad Saulgau. It is a world-ranked ladies tennis tournament featuring $25,000 in prize money. A total of 2500 visitors attended the tournament. The first seed, Maryna Zanevska, won the tournament in front of 600 spectators. The 20-year-old Ukrainian thus makes a small jump on the world rankings list and is aiming to qualify for the US Open. The KNOLL OPEN has established itself as a tennis highlight in Upper Swabia. And it's not for nothing that it was awarded the title of best international tournament in the German Masters Series this past November. This prize honors the effort required for the organization of a perennially successful event. The reaction to the tournament can also be determined from the number of visitors to the website: 26,742 visitors with 250,623 page calls, meaning that on average, each visitor informed himself about the tournament standings 10 times. In addition, there were 23,358 live stream calls, indicating that some spectators were also watching "live" on their computer screens.




With KNOLL GESUND, the outlook is brilliant

There was a lot happening at KNOLL GESUND in the spring/summer: from cooking workshops to spinning classes to kickboxing, aerobics and suspension training. A special highlight was the climbing event in July in the Naturpark Oberes Donautaul in Beuron-Hausen. Under the leadership of a qualified guide, five employees tested their courage and their limits and demonstrated teamwork and responsibility in the course of this activity. After a warmup program and a thorough safety training, the climbing program started on secured and suitable rocks. After the climb, the group was rewarded with a beautiful view from the top of the rocks. The descent was suspended but well-secured, featuring slow rappelling. There will also be numerous offerings in the fall. Some of the courses mentioned above will continue. The next KNOLL GESUND flyer will provide an overview of all courses; it will be sent out after the vacation period ends.





Aid project provides people in Burkina Faso with hope

KNOLL has supported educational projects in Burkina Faso with its "Mangos for Education" campaign since 2009. The "Hilfsfonds Burkina Faso e.V." association imports 80,000 mangoes a year and sells them in Germany via partner vendors; our company is one of these. The association collects all of the revenue, using it to provide aid in Burkina Faso. This way, a new school or vocational school is created every year. At the same time, the project assists employees on-site by paying them 20 cents per mango washed and packed. This nearly doubles their average annual salary. The revenue for Burkina Faso from the sale of mangoes at our company amounts to approximately EUR 2500. The project is organized by our trainees. They are responsible for the individual departments' orders as well as for the overall order. This year, 400 cartons of mangoes (with approximately 8 - 11 fresh mangoes per carton) were ordered, plus approximately 750 packages of dried mangoes.

Change of perspectives

KNOLL is participating in the program "Inclusion in Upper Swabia". In the spring, KNOLL trainee Julian Bechtle worked closely with Marcus Baumgärtner for one week in the Upper Swabian Workshop for the Disabled (OWB) in Mengen. Baumgärtner then came to KNOLL for one week. The exchange was part of the "INIOS – Inclusion in Upper Swabia" program. The project "Change of perspectives" allows trainees in regional companies to spend one week in a workshop for people with disabilities (WfBM) and in return, it allows people with disabilities to work one week in regional companies. KNOLL training manager Peter Widmann believes this is a positive development: "We learned a lot. Readiness to help others, openness and acceptance of one's fellow people who are different have increased substantially." Julian Bechtle sees things similarly: "For me, the cooperation with Marcus was enriching, especially the warm interaction. Surprising was that products and quantities similar to what we produce in chipping were also produced there." Managing Director Matthias Knoll is convinced: "Interpersonal skills are important to us. The exchange offers outstanding possibilities for gaining practical experience. Starting in the coming year, we would like to expand the project to all trainees and naturally also invite other employees of the OWB to visit us." For more details about the exchange week, see:


What is inclusion?


Everybody should have the opportunity to participate completely and equally in all social processes. A milestone here was set by the UN convention on the rights of persons with disabilities, which went into force in Germany in 2009.


What is INIOS?


"INIOS - Inclusion in Upper Swabia" is a program for inclusion in work and the creation of inclusive life and working worlds where the differences between people are the rule. The project initiators are the Institut für Technik und Arbeit (ITA) and a series of other participants. The project is supported by the "Aktion Mensch."


Incorporated: VLO filter technology

KNOLL supplied the filter system technology for a manufacturer of transmissions and gear sets. The vacuum filter VLO 300-2 was selected. The VLO is especially well-suited for the production of gear sets and here for the the processing of abrasive fabric. In addition, these filters' compact installation space fits well in the available space. The KNOLL system was incorporated into an existing machine design and replaced the previous system. In order to guarantee a smooth transition, KNOLL integrated some components from the existing system and ensured the adaptation to the existing control design.

Inspired: Training Day

Approximately 450 visitors accepted the invitation to KNOLL's training day on April 5. Visitors included pupils from a wide variety of different kinds of secondary schools, as well as interested parents. The visitors were assisted first and foremost by the highly motivated KNOLL trainees. Training is greatly valued at KNOLL. The goal of this annual event is to present the training possibilities at KNOLL "live" and on-site. A brief tour with presentations of the company and its products provided an overview of the entire company. Visitors were able to learn more at various information booths about the individual professions for which training is offered, the talent pool, and personnel development at KNOLL. The offerings were rounded off with the AOK. At the AOK booth, visitors received advice on health topics and they could take a balance and coordination test on the balance board. The visitors were obviously inspired by the well-tended and bright facilities, the first-class machine park, and the many and varied offerings for trainees and employees.


New: the Personnel Office

Detecting trends and anchoring them at the company, transferring market conditions into solutions – KNOLL has restructured its personnel department in order to accommodate the growing number of employees. We regard this as an appropriate response to demographic change and the resulting scarcity of trained workers. KNOLL would like to be a business partner for its current and future employees.


Purity law? Clearly.

KNOLL advertisement 2014

We Swabians place great value on cleanliness. This is why we take the purity law very seriously. When we are drinking our beer in the evening and for our first-class filter products during the day: the MicroPur® superfine filter is a winner with its great filter fineness (1-3 μm). This is how dirty oil becomes clear.

KNOLL training - still developing

Qualification is the foundation of personnel development – the current KNOLL training catalog begins with these words. The management would like to encourage employees to take advantage of the extensive offerings. There are many development opportunities for everybody.


KNOLL talent pool - coming right along

At KNOLL, employees with particular abilities have long been encouraged to develop these. In order to increase the number further, we have reworked the previous talent pool concept. The program is aimed at employees of all ages from all areas of the company, regardless of whether in Administration or Production. A defined selection process and a committee decide who will be included in the talent pool.





KNOLL at Trainee Marketplace - get still closer

At the beginning of February, the KNOLL trainees attended the professional information exchange "Trainee Marketplace." In January, there was a workshop at KNOLL, "Trade show training for trainees." The trade show in Bad Saulgau's vocational school center offered the KNOLL trainees the opportunity to gain some experience presenting the company. Required were first and foremost the training professions and the product portfolio. A KF filter served as a trade show exemplar. The reaction was positive and chance brought a group of English-speaking exchange students from France to the KNOLL booth. Therefore, there were also conversations about the topic of training in English.


KNOLL system technology - still more flexible

A well-known manufacturer of CNC machines, metal carbide and diamond tools has selected KNOLL for its system technology. For even in the early planning phase, KNOLL was able to guarantee a great deal of flexibility. A challenge for the project was the constantly increasing production capacity of this rapidly-expanding company. The modular basic concept offered the opportunity to react to capacity changes in the course of the project with custom-tailored solutions. In addition, an interim solution for a transition period was provided on loan. The system, when fully installed, currently has a filtration capacity of 980 l/min and it can be expanded to 1900 l/min. The expansion is already prepared; it can be implemented without production downtime.

Systems engineering with distributed functions

KNOLL supplied a camshaft manufacturer with a central filtration system for its grinding operations. The material in question is through-hardened and induction hardened steel. The scope of services provided by KNOLL included the delivery and placement from the foundation up, as well as installation of the cooling lubricant supply system complete with the pipework in the cooling lubricant plant. The systems engineering comprises a modular filtration system with up to 4 vacuum filters; spacesaving cylindrical tank systems for storage and refilling of cooling lubricant; a materials handling system for the removal of grinding sludge and automatic filling of containers; a temperature control system with 300 kW refrigeration capacity, and a fluid centrifuge for bath maintenance. A briquetting press supplied by the customer for the recovery of machining oil rounds off the fully automatic cooling lubricant treatment and grinding sludge disposal system. The installed filtration stages are: a full-flow filtr tion stage via a continuous conveyor belt (20 μm), a partial-flow bypass filtration stage for spindle cooling (5 μm), and a bypass filtration stage for bath maintenance including centrifuge (3 μm). KNOLL came through with flying colours by delivering modular systems engineering without filtering agents and an integrated concept tailored to the customer's specifications. Both parties sealed their mutual trust in the form of a five-year contracting agreement . KNOLL will assume the role of plant operator over the contract term and, therefore, will be responsible for all inspections and maintenance work necessary to ensure trouble-free operation.

Integrating a transport system flexibly

The TSS transport system by KNOLL is now being used to good effect by a producer of high-performance polymers seeking to make its production process even more efficient. The customer was searching for a system that is flexibly adaptable to the production process and expandable on a modular basis. The TSS transport system meets all these criteria. It is used after the polymer curing process in the oven. The mould and the carrier pallet are transferred to a TSS truck at a transfer station. This truck is conveyed to a cooling zone comprising a conveyor belt with six buffer stations. Here, an enclosure with two high-speed gates ensures that the material is uniformly cooled. The heat which is released in this process is piped into the customer's heating system. Separate scissor-lift tables with a rotator unit remove the polymer mouldings so the moulds can be cleaned and prepared for the next process cycle. An additional enclosure is used for cooling the large plates.

Pumping foodstuffs gently

A manufacturer of high-quality soups chose an MX progressing cavity pump for processing its products. The products in question are known for their fresh ingredients sourced from market halls in Munich. To ensure freshness, ingredients are processed immediately and conservatively. As a matter of principle, no additives or preservatives are used. The MX progressing cavity pump meets the customer's requirements to the full. It pumps and dispenses ingredients freshly and gently. Outstanding features of the MX pump include its enlarged suction housing with a nominal width of DN65 and its free spherical passage which allows particles up to a size of 22 mm to pass through. This allows chunks of both meat and vegetable to be pumped gently and without damage. The application involves handling a solids content of up to 25%. Other features of the pump are a max. pressure of up to 10 bar as well precision dispensing and control by means of a servo gear motor.

KNOLL relies on performance

The construction at KNOLL continues. The goal is a sound future for the production location Bad Saulgau. Impressive figures for the street and land-exchange measures alone lie behind the new construction project: the construction site is approx. 14,500 sqm large and thus larger than two official soccer fields. In total, approx. 2700 cubic meters of soil were carried away; most of this has already been used for re-cultivation. Approximately 80 to 100 truckloads were stored temporarily so that a large green space can be created after completion of the construction project. The construction site digging produced approximately 1300 truckloads full. The delivery and installation of sound gravel and pure recycled concrete material filled approximately 2000 truckloads. The new street areas created are nearly 2800 sqm large.
