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.

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.

The Infinity ToughLine press fabric maintains its consistently high void volume even when exposed to high line load and substantial degree of wear. A constant water flow guarantees consistent performance over the entire life of the fabric.

  • For use in particularly challenging environments
  • Simple and fast seam closure
  • Successfully tested at Chinese paper mill

ToughLine – as the name suggests, is the new range of press fabrics from the Voith Infinity family specifically designed for use in extreme environments. These conditions occur, for example, when manufacturing pulp, board and packaging papers, where the fabrics are continually exposed to heat or abrasive materials. Nevertheless, they have to reliably drain the paper webs and perform consistently in the process. Paper quality deteriorates as soon as fabric structures become compacted during operation.

Voith offers Infinity ToughLine with and without seam. The modular structure of the fabric means that it can be tailored precisely to customer requirements.Voith offers Infinity ToughLine with and without seam. The modular structure of the fabric means that it can be tailored precisely to customer requirements.

Voith uses the latest weaving technologies which produce a genuinely laminated structure to avoid this compaction in its Infinity ToughLine press fabrics. This enables the fabric to remain very stable in both MD and CD over its entire life and to constantly retain its high void volume. Good compressibility and excellent resiliency also give the press fabrics a high dewatering capacity. The stable high void volume of the fabric and its drainage capacity ensure minimal dirt deposits, creating the basis for a consistently high paper quality. Voith offers Infinity ToughLine with and without a seam. The modular structure of the fabric allows it to be tailored precisely to customer requirements.

Successfully tested
A Chinese paper manufacturer was one of the first of Voith's customers to test Infinity ToughLine with a seam. The company’s conclusion is that the time for changing the fabric is cut in half. Previously, the paper producer had used conventional endless fabrics. However, these are very time-consuming to change and also present safety risks. If a seamed fabric is used instead of an endless fabric, there is no need to open the whole machine. The new fabric can be easily joined with the old fabric and pulled into the machine where it can be closed. All Infinity ToughLine seam loops are of identical loop length, shape and spacing, joining the seam is quick and easy.

Even though the use of seamed fabrics offers great savings in time and costs, many paper manufacturers continue to rely on endless fabrics. They are concerned that the seam will leave marks on the paper and therefore cause additional waste. Meanwhile, market experience with Infinity ToughLine shows that the new press fabric does not leave any marks on the paper web over their entire life and ensures a consistently high paper quality. Convinced of the results, the Chinese paper producer has converted its machine entirely to fabrics with seam in the meantime.

Infinity ToughLine is available with PeakElement the elastomer component available for all Voith press felt designs. Infinity is part of the PressMax range of Voith AdvancedPRODUCTS. Alongside individual products, PressMax offers papermakers the opportunity to enhance the performance of their paper machine through the ideal combination of perfectly matched products.
