Voith's innovative CleanLine traversing cleaning systems for fabrics provide additional benefits for customers compared to established cleaning methods.

With CleanLine, Voith has developed its systems to improve paper quality by thorough cleaning of the fabrics.  CleanLine systems are available for all sections of the paper machine either as new installations or as upgrades of existing Voith equipment to remove more contamination from the surface and structure of fabrics. The CleanLine systems work in combination with other Voith products to improve the productivity, runnability, safety and quality of the paper making process.

Voith has just introduced CleanLine Extract4D in the drying section for packaging and newsprint paper grades made from recycled fiber.Voith has just introduced CleanLine Extract4D in the drying section for packaging and newsprint paper grades made from recycled fiber.

Maintain Fabric Performance
Clean fabrics are essential for the removal of moisture from the paper web and for achieving the required properties of the finished paper. Voith CleanLine Systems are effective in maintaining the performance of the fabrics and are a cost effective solution to reduce the effects of contamination.

Leading Technology
CleanLine Excell – Forming: by cleaning in two directions with a close concentration of fine water jets the forming fabric is much cleaner. Uniform performance of the fabric is achieved because Excell can more easily remove different levels of contamination across the fabric width. The system uses only about 10 percent of the water volume compared to an oscillating high pressure shower and runs on key reference machines in Europe, America and Asia.

CleanLine Excell – Press: has a selection of different cleaning heads for additional cleaning of press fabrics and transfer belts to solve specific problems with contamination, cleaning chemicals or profiles.

CleanLine Extreme from Voith can automatically switch between on-line and off-line cleaning to keep the fabrics in good condition.

CleanLine Extract4D – Dryers: has just been introduced for packaging and newsprint paper grades made from recycled fiber. Up to four directions of water jets directly contact and remove more contamination from the fabric. This unique system has resulted in better runnabilitry on both packaging and newsprint machines due to cleaner fabric surfaces and higher permeability retention.

CleanLine Extreme – Coaters: is a new system for cleaning tensioning fabrics, running successfully on more than 20 top and bottom sections. Productivity is improved because the system can automatically switch between on-line and off-line cleaning to keep the fabrics in good condition. Highest quality of the coated paper is achieved by using an extended air-knife and option of a heated air blower to ensure that the fabric surface is dry when it contacts the coated paper.

Servolution
With Servolution, Voith is offering customized service packages to improve the performance of its customers and help them increase their productivity. The holistic approach, modular design and easy access to components in the CleanLine systems provides efficient servicing and management of spare parts from a single supplier. Voith provides a comprehensive support package to ensure the highest availability and performance of the cleaning equipment. 

The quality of raw material for making paper faces many challenges in the coming years. Voith’s process know-how, understanding of fabrics and wide experience of fabric cleaning systems makes CleanLine the complete solution for fabric cleaning.

The installation of a new NipcoFlex shoe press was part of a comprehensive modernization of the Macedonian Paper Mills in Thessaloniki, Greece. With its help, the company was able to improve the quality and quantity of paper production. At the same time, the use of Voith technology reduced the plant's use of resources and therefore improved the company's competitiveness.

  • Better board quality and runability a key criterion
  • Voith's integrated overall concept impresses board manufacturer
  • Detailed advance planning and close collaboration allow smooth rebuild and production start

The installation of a NipcoFlex shoe press was the first step in a comprehensive rebuild of the BM 1 at Macedonian Paper Mills (MEL) in Thessaloniki. This measure allowed the internationally operating manufacturer of board and packaging papers to increase machine production by 15 percent. But this increase is only one of the goals of the upgrade, as Georgios Georgiadis, the manager of the board factory, explains: “With the new press section we were able to improve board quality characteristics, reduce breaks and therefore significantly increase machine availability.” MEL mainly produces paper for packing foodstuffs on its BM1. In this segment, good printability is a major criterion. The investment in the new press section is therefore an important first step towards meeting customer requirements in the long term.

The NipcoFlex technology used on the BM 1 reliably corrects deviations in the CD profile and ensures a uniform thickness across the entire 4.110 millimeter wide paper web. A large Yankee cylinder and a coating system with drying function improve the smoothness of the surface.

One challenge associated with modernizing the plant was the tight time frame. The Voith service team had just three weeks to complete the project. Thanks to good preliminary planning and the smooth collaboration between all participants the BM 1 could be restarted on 23 July 2017. As the team from MEL was not familiar with the shoe press technology, comprehensive training including visits to similar systems was conducted in the run-up to the rebuild.

As well as improved paper quality and increased production, the new press section offers another advantage: The BM 1 now needs much less steam, which reduces the energy consumption of the machine. Despite this saving in resources, the NipcoFlex technology also enables a higher dry content in the paper web.

Several factors prompted MEL to work with Voith on this project. One of the key aspects was that Voith has more than 150 years of experience in building paper machines, is a technology leader in many areas and is renowned for the high reliability of its products. In addition, MEL has already worked with Voith on numerous projects, the results of which have been consistently positive for the board mill team. Ultimately, Voith also convinced the customer with an overall concept that was integrated technically and financially. That this was the right decision was not just confirmed by the smooth start to production.

“The atmosphere between the individual teams was excellent. The close collaboration with the colleagues from Voith Tolosa even resulted in some friendships,” says Georgiadis, adding: “I will certainly recommend collaboration with Voith to colleagues in the paper and board industry.”

The project is part of a comprehensive upgrade by the board mill. For example, MEL is investing in its own biomass power plant, which not only supplies power to the paper machine but is also used for steam generation.

In Schwedt, Voith has converted the LEIPA Group’s PM 5 from a newsprint to a packaging paper machine. On 19 April 2018, the acceptance and handover of the machine of the Schwedt PM 5 project was signed early at LEIPA Georg Leinfelder GmbH, with effect on 13 April. As a result, the Voith team on site managed to bring the entire machine, consisting of a BlueLine OCC stock preparation line, DIP stock preparation line and XcelLine paper machine up to handover quality just 19 days after ‘stock on wire’.

Perfectly matched components and an extensive automation system including OnQ quality control system make the machine a new benchmark in the industry. LEIPA can produce approximately 450,000 metric tons of white top testliner (WTTL) on the machine and is therefore the market leader in this segment. After taking over the UPM mill in Schwedt, the new owner, the LEIPA Group, decided to extensively rebuild the existing PM 11. Under the management of Voith, the conversion of the newsprint paper machine to a machine for the production of white top testliner (WTTL) began in October 2017. LEIPA invested over 160 million euros in the plant. Now known as PM 5, the machine is a new point of reference for packaging paper. Just a few machines worldwide surpass its 9,200-millimeter wire width. It also takes the top spot with its production speed of 1,200 meters per minute. LEIPA plans to produce 1,180 to 1,400 metric tons of white top testliner per day with the best surface properties and basis weights of 100 to 140 grams per square meter. LEIPA wants to manufacture a total of 450,000 metric tons of paper every year and thus expand its market position further.

Optimized for high speeds
To ensure the PM 5 can meet the desired output and quality requirements, Voith modified almost every component of the existing machine. A new hybrid former with two headboxes DuoFormer D and TopFormer F replaced the previous former, for example. Voith also developed a comprehensive solution for the transition to the press section and for the press, with a DuoCentri NipcoFlex shoe press in the center. These two components were designed to meet the requirements in high speed machines and enable outstanding product quality. Robust SolarPress roll covers assist in achieving this. The covers do not require any water cooling and help LEIPA to conserve resources. The SpeedSizer AT is also optimized for the uniform and faultless application of starch at high speeds.

During the rebuild, Voith separated the existing dryer section into a pre-dryer and after-dryer section. In the process, the pre-dryer section received a completely new TopDuoRun dryer group, while existing components were used for the after-dryer section. Thanks to a new MasterReel reel and the rebuild of the two existing DuoRollers, reel diameters of up to 3.5 meters can now be produced on the PM 5. The existing machine hall ventilation system was also expanded and integrated into the new process and quality control system.

15,000 recorded signals ensure optimum paper quality
Some of the existing motors were also used after the conversion. However, the Voith team integrated more than 333 new motors of different sizes into the PM 5, the most powerful of which has a capacity of 1.5 megawatts. Most of the motors are integrated into the automation concept developed by Voith. The system records more than 15,000 signals, monitors all the production steps from stock preparation to the reel, reports even the slightest deviations and levels out any fluctuations within a fraction of a second where needed. 29 state-of-the-art computer processors take care of processing the information. “The continuous data stream forms an important basis for us to maintain a consistently high paper quality at all times”, says Falk Friedrich, Plant Manager of LEIPA Schwedt Nord.

Increased efficiency for paper treatment
While the rebuild was taking place, a new machine for the efficient treatment of up to 1,400 metrics tons of fiber from recovered paper per day was also built. With a length of 50 meters, a diameter of 4.5 meters and a total weight of about 200 metric tons, the IntensaDrum pulping drum is the largest Voith has supplied to date. Much of the existing deinking system (DIP) was retained. Voith only had to modify it to cope with the characteristics of packaging papers. Among other measures, the technology group installed energy-saving components for bleach and flotation, which, along with the new cleaning system, reduce fiber losses.

“The engineers from Voith view the system from the apron conveyor to the winder, including measuring, automation and ventilation technology as a whole, and therefore develop perfectly compatible solutions”, emphasized Martin Kaltenegger, Project Manager for LEIPA PM 5.

Voith clothing for optimum performance
In addition, the order volume included start-up and a number of training sessions in which the LEIPA team became familiar with the intricacies of the PM 5. Voith will remain closely involved in the processes of the PM 5 after start-up too. In the next few years, the single-source supplier will deliver the clothing and doctor blades for the machine and thus ensure the optimum performance of the PM 5. The optimization of the machine within the first eight weeks after start-up is also part of the project – with an option to extend it for longer. “The entire project, from the shutdown of the PM 11 to the installation of the new components and start-up of the new PM 5 has gone very well. With their professionalism and dedication, the two project teams have ensured the success of the project”, says Robert Osswald, Project Manager Voith Paper.

High dewatering efficiency and long service lives have made press fabrics from the Voith Infinity series best-sellers for packaging papers, board and graphic paper grades. The technology group has now extended its product range. Infinity FineLine offers an ideal solution for sensitive applications like tissue or specialty papers. The modular structure of the press fabrics allows easy adaption to any requirement.

  • Minimized seam loops at consistently good closability
  • Highly durable when combined with twisted yarn
  • Energy efficient through low grammage

With its new FineLine module, Voith is further expanding its successful range of Infinity fabrics. For the new products, a particularly fine loop structure was developed and the seam zone was further improved. FineLine is mainly used in the tissue and specialty paper segment. The new press felt is available as endless and seam product. Infinity FineLine debuts with remarkably minimized seam loops that reduce marking potential even in the finest papers. As with all Infinity products, the seam loops in FineLine also have an identical loop length, roundness and spacing. This makes the closure particularly simple and enables machine downtimes to be reduced by up to 25 percent.

For Infinity FineLine, an especially fine loop structure was developed and the seam zone was further improved. This is why these press fabrics are used above all in the tissue and specialty paper segment.For Infinity FineLine, an especially fine loop structure was developed and the seam zone was further improved. This is why these press fabrics are used above all in the tissue and specialty paper segment.

A combination of Infinity FineLine and twisted yarns has proven particularly advantageous in sensitive applications. The twisted yarns ensure better batt fiber anchorage. As a result, the paper producer benefits from consistent performance over the entire service life. At the same time, Infinity FineLine is specifically energy efficient through its low grammage.

Cohesive range for all requirements
Alongside FineLine, the Infinity series also includes the ToughLine range of fabrics which Voith designed specifically for extreme environments. These conditions occur, for example, when manufacturing board and packaging papers, where the felts are continuously exposed to heat or abrasive materials. The use of Infinity press fabrics for the production of graphic papers is also constantly increasing. “Our Infinity series offers the best press felts portfolio for all paper machine requirements”, says Anne Klaschka, Global Product Manager Press Fabrics at Voith. The modular structure of the fabrics means that they can be tailored optimally to customer requirements.

The Infinity series is part of the PressMax portfolio of the Voith AdvancedProducts range. It allows paper makers a combination of perfectly coordinated components to improve the performance of their paper machines.

A narrow time window, a size press operating at its maximum speed and the need for greater machine efficiency were the various challenges faced by the Voith team as it tackled the upgrade of the PM 6 at Smurfit Kappa. Thanks to excellent planning beforehand, the machine was restarted without problems one day ahead of schedule.

  • SpeedSizer AT extends the operating window for packaging paper production
  • Reconditioning of existing Nipco deflection compensation rolls
  • Smooth startup with new components

“The startup of the new SpeedSizer has shown how expertise and dedication bring about an excellent outcome. The project simply flew by,” says Jochem Meier, Manager Operations at Smurfit Kappa in Zülpich.

Smurfit Kappa wanted to achieve a higher production speed through its modernization of the PM 6 at the Zülpich mill. The company is one of the leading manufacturers of packaging in Europe. At its facility in Zülpich it produces premium quality testliner and recycled fluting in basis weights of 100 to 150 grams per square meter from 100 percent recovered paper.

Because the machine was only supposed to be shut down for a week for the conversion, detailed advance planning was absolutely essential for the success of the project. The excellent longstanding relationship between Voith and the customer facilitated this planning. For example, Voith’s service team had previously carried out maintenance on the PM 6 on an ongoing basis. However, the narrow time frame was just one of the challenges.

A key aspect of the project was the puddle-type size press. Equipped with a deflection compensation roll, it allowed an optimum CD profile of the nip load (linear contact pressure) and for a long time had guaranteed the high quality of the paper. But for technical reasons, the size press limited the production speed of the PM 6 to 1,150 meters per minute. Even though the size press was one of, or perhaps even the fastest in the world, it prevented the machine from being ramped up to the 1,225 meters per minute desired by the customer.

This is why Voith recommended installing a customized SpeedSizer AT with the existing Nipco deflection compensating roll system. This application system enables excellent coating and size profiles even at high speeds. Its use increases the operating window of the PM 6 and offers Smurfit Kappa more production flexibility. The SpeedSizer ensures an increase in the solids content of up to 17 percent and reduces the moisture ingress into the paper web. This results in a higher dry content downstream of the SpeedSizer AT, which helps substantially reduce drying energy and achieves much improved paper web running properties.

Voith SpeedSizer AT PM 6 Smurfit Kappa ZülpichVoith SpeedSizer AT PM 6 Smurfit Kappa ZülpichVoith used a Nipco roll that was already being used in the old puddle-type size press as a deflection compensation roll. Following comprehensive reconditioning, they now also ensure optimum CD profiles and consequently high paper quality in the new machine as well. The re-use of the previous rolls reduced the costs of the upgrade.

The new SpeedSizer AT plays a major role in reducing the energy consumption of the PM 6. Immediately, a 15 percent reduction in steam consumption could be achieved. The specific energy figures are of course also improved as a result of the higher production rate. A good startup is extremely helpful, because the completely closed water circuit at SK Zülpich Papier has to be evaporated again after a week of shutdown.

The use of the new UniFilm T applicator roll cover, which is very wear-resistant, ensures good metering rod service life and more efficient production. In the PM 6 they run for more than 400 hours, well above the average for comparable machines.

An audit conducted with customer in the run-up to the project went a long way to ensuring that the rebuild on the BM 3 in Arnsberg was completed ahead of schedule. Not only did the close collaboration between the two companies deliver a three percent increase in productivity and an improvement in paper quality; the costs of the rebuild were also reduced due to the re-use of components.

  • Extensive audit performed ahead of project planning
  • Higher productivity and reduced use of resources
  • Rebuild completed sooner than planned

In an email of thanks to Voith's project team, Thomas Bock, Managing Director of the RDM Group, wrote: "I just wanted to let you know that the BM 3 in Arnsberg has been producing board since 6:50 pm. This means that we have more than achieved our goal." Voith had completed the extensive rebuild of the board machine a day ahead of schedule, allowing RDM to resume production earlier than planned.

A crucial factor in the success of the project was the extensive audit conducted jointly by Voith and RDM beforehand with the involvement of numerous experts from various areas. Together, the parties defined the goals to be met by the rebuild and the measures necessary to achieve them. The reduction of manufacturing costs was a key objective for RDM, so the partners explored various options in order to jointly work out an ideal solution.

They determined that the best starting point for optimization was the intermediate ply of the three-ply cardboard produced on the machine. To stabilize the quality of the surface RDM had to use an expensive top layer. To prevent flutter, new components, for example, were designed to reduce the consistency in the headbox from up to 3 to 1.5 percent. As a result, RDM is now able to use a more cost effective top layer.

The participants did not always opt for the variant with the lowest investment cost. During the audit several options for the dewatering elements had been tested, whereas the decision was made in favor of the most forward-thinking variant. The chosen solution reduces fluctuations that are usual downstream of the headbox and therefore creates the basis for the high product quality. One cost-saving measure was to use as many parts from the BM 3 as possible for the rebuild. So during the audit the two companies determined which components were worth re-using.

A crucial factor in the success of the project was the extensive audit conducted jointly by Voith and RDM beforehand with the involvement of numerous experts from various areas.A crucial factor in the success of the project was the extensive audit conducted jointly by Voith and RDM beforehand with the involvement of numerous experts from various areas.

Extending the dewatering section with an improvement in dewatering capacity also proved to be an expedient measure. Only a short time after the restart the production speed increased by 3 percent. The intermediate ply is not the limiting section anymore as it is designed now for 1000 m/min.

Not only did the rebuild result in a reduction in production costs; Likewise, the fiber savings and higher dewatering capacity also improved paper quality. "It was the best execution of a project I have witnessed in Arnsberg in the past 37 years," RDM Product Manager Joachim Corthum also confirmed.

The fact that production could restart ahead of schedule thanks to the well-coordinated collaboration between all parties during the planning and rebuild phases has also prompted RDM to get Voith on board for other servicing projects.

When upgrading its PM 2, Koehler Kehl opted for products from Voith's AdvancedPRODUCTS range that enable the company to reduce the machine's water consumption, achieve a faster starting curve and at the same time improve paper quality.

One of Koehler’s major strengths is its willingness to constantly improve. This is why for the upgrade of the press section on the PM 2 the focus was on achieving more stable operation, reliable planning of shutdowns and improved safety in the production process. On the PM 2, the company produces just short of 130,000 metric tons of thermal paper per year with basis weights of between 35 and 47 g/m².

Wiebke Petzold (Voith Product Manager) and Joachim Fuchs (Productionmanager PM 2 / CM 2 at Koehler Kehl Germany) at the PM 2 in Kehl.Wiebke Petzold (Voith Product Manager) and Joachim Fuchs (Productionmanager PM 2 / CM 2 at Koehler Kehl Germany) at the PM 2 in Kehl.

In the course of various improvement measures, Voith fitted the press section with products from PressMax range of its AdvancedPRODUCTS. The prime objective was to continually improve the quality of the paper grades and reduce its operational costs.

The latter was especially achieved by using of the QualiFlex press sleeves for the shoe press. Refinements were made to the sleeves and their abrasion behavior was improved. On the PM 2 this led to a doubled runtime. This reduced the maintenance work for replacing the shoe press covers. Previously, the press sleeves had needed to be changed after 180 days on average.

An increase in productivity was also the reason for introducing press felts with PeakElement which allow a faster start and better nip dewatering than standard felts. As a result, the start-up curve of the machine could be shortened considerably following the felt change. “With the installation of the Voith products, we were able to clearly improve the start-up curve after felt change on the PM 2. The machine can be brought to its maximum speed faster and with fewer problems, resulting in greater availability and lower operating costs,” states Joachim Fuchs Productionmanager PM 2 / CM 2 at Koehler Kehl Germany.

In addition, the measurements taken by the FeltView system delivered important moisture and permeability data for targeted conditioning of the pick-up felts. Koehler can use this data to continually optimize machine settings and improve efficiency. Critical felt conditions can be identified before they impair the process and the felts are run in optimum operating condition. FeltView also makes manual measurements redundant, which ultimately improves the safety of the production process.

Voith Paper concluded, in October, the start-up of the new XcelLine VTM 3 tissue machine it has supplied to US tissue and specialty paper manufacturer Little Rapids Corporation. The new machine has replaced the company’s old PM 3 at its Shawano production facility in Wisconsin.

The new VTM 3 went online six days ahead of the contract schedule, thereby achieving a total plant downtime of just 30 days from paper to paper, that is, between dismantling the previous equipment and erecting and starting-up the new machine. Besides this outstanding achievement, the second jumbo roll of tissue paper already provided marketable quality, and the machine reached its maximum operating speed during its first week in service.

All of the new VTM 3’s technologies and components are seamlessly coordinated and integrated with each other. Besides the new XcelLine tissue paper machine and its auxiliary equipment – not counting the Yankee cylinder, which has been reused from the old machine – Voith’s scope of supply also included stock preparation and approach flow systems, a steam box, a gas hood, and a mist removal and dust reduction system. The order was rounded off by Voith's automation package, comprised of the DCS and MCS systems, as well as field services.

This project’s key benefits include an improvement in paper quality and increased production capacity, since the new machine will now be producing at a speed of more than 1,800 meters per minute.

All of these measures are not only indicative of the project’s enormous success, but also the outstanding synergy between the Voith, Little Rapids Corporation, and Contract Companies teams. “We are extremely proud of the teamwork demonstrated by all parties involved to safely execute the rebuild within a very compressed timeframe. We are also encouraged by the performance that we are seeing at this early stage of the machine’s start-up ramp and optimistic that this investment will provide additional capabilities and quality enhancements that our customers value,” said Ron Thiry, Vice President and General Manager at Little Rapids Corporation.

A consistently high quality for all basis weights and low energy consumption were the two main requirements to be met by the new PM 1 at Kipaş Kağıt. This is why the Turkish paper manufacturer opted for an XcelLine system from Voith featuring a high degree of automation.

  • Efficient production of high-quality board and packaging papers
  • Basis weights from 90 to 400 g/m2 possible
  • Automation package guarantees process reliability

voith logo 2013At the end of September 2017, Voith won a contract from Turkish paper manufacturer Kipaş Kağıt to build the PM 1 at the company's mill at Söke in Western Turkey. The company will use the XcelLine facility to produce around 700,000 metric tons per year of high-quality board and packaging papers with basis weights of 90 to 400 grams per square meter. Kipaş Kağıt is planning to run at a production speed of 1,200 meters per minute. The wire section has a flexible design allowing the production of two-ply and three-ply paper.

One of the key priorities for the Turkish papermaker was high paper quality with high machine efficiency even in the case of low grammages. In addition, the machine should be particularly energy efficient, i.e. use less power, water and steam. XcelLine meets both these criteria thanks to its perfectly matched components.

In the stock preparation unit of the PM 1, for example, various products of the BlueLine family reduce the costs for energy, fresh fiber treatment, water and maintenance. In four stock preparation lines featuring processing technology specially designed for various recovered papers and pulp and with a total production capacity of more than 3,000 t/day, the conditions have been created for manufacturing high-quality paper products. Apart from the process machines, Voith will also supply the complete water, sludge and reject system and the main components for the effluent treatment plant.

Stock distribution is done via three MasterJet Pro headboxes. The OnQ ModuleJet dilution water system, which is integrated into the headbox for the middle ply, allows the dilution water to be dosed directly into the intermediate layer. This results in a uniform distribution over the entire height of the layer. The system improves the accuracy of the control response in the paper web by over 50 percent compared with conventional systems, allowing optimum CD profiles and an excellent fiber orientation to be achieved.
A key element of the Combi DuoRun dryer section are the EvoDry steel cylinders which allow the number of drying cylinders in the pre-dryer and after-dryer sections to be reduced. This reduces the weight of the dryer section and saves investment and electricity costs, without compromising the quality of the products.
In addition, the PM 1 will be fitted with a Tandem NipcoFlex shoe press with four felts and a downstream third press to improve smoothness, a SpeedSizer AT film applicator unit and an EcoCal Hard and EcoCal Soft nip calender. If the paper is to be coated this is done using up to three DynaCoat AF coaters and a DF Coat unit for direct coating. Non-coated papers are transferred via an intermediate Sirius winding system directly to the two VariFlex winders with two-drum winder technology. Voith will also supply the complete initial clothing for the PM 1 and three further clothing sets.

A comprehensive automation package consisting of OnControl process control system, OnQ quality control, OnView information system and OnCare CM condition monitoring increases process reliability and allows preventive maintenance. Interminable and costly machine shutdowns can therefore be avoided. Moreover, the OnV energy management system that is also integrated into the PM 1 identifies, localizes and visualizes all energy consumptions during ongoing paper production and offers the user numerous options for improvement. In this context, the entire machine air system, which guarantees high heat recovery rates and operational reliability, makes an especially important contribution to energy saving and economic efficiency.

The good experience that Kipaş Kağıt had with Voith in the past during the construction of the new stock preparation unit in 2013 was the reason the company decided from the very outset that the new facility had to come from one source. The Turkish paper manufacturer was more than satisfied with the performance and reliability of the stock preparation unit and therefore decided to award Voith the entire contract for the PM 1 and also entrust the technology leader from Heidenheim with the complete planning of the facility. As part of its Process Line Package, Voith assumes total responsibility for the project and guarantees scheduled completion of the system at the agreed price.

Moreover, Kipaş Kağıt is planning to work with Voith again to build another paper machine for non-coated packaging papers in the same width and with a similar production capacity at the same location.
