With NanoGloss, Voith brings a new calender roll cover onto the market that combines two important characteristics: a high level of mechanical stability and a high level of gloss on the paper. In its first field tests, the new cover achieved impressive results with an increase in gloss points. The paper produced with NanoGloss stands out with its high level of gloss and uniform smoothness.

NanoGloss is a multilayer roll cover which can be used in all positions on super, soft and multi-nip calenders. The proven, innovative finer surface topography achieves a high level of gloss improvement. In contrast to conventional calender roll covers, NanoGloss retains its exceptional surface characteristics between each regrind. The matrix structure of NanoGloss also guarantees the highest levels of stability and resistance. Furthermore, NanoGloss can be repaired just as easily as any other Voith calender roll cover.

Thanks to the characteristics of the new calender roll cover, inflexibility, wear and damage are prevented. Paper manufacturers can therefore enjoy reliable operation with NanoGloss.

Voith has supported Schumacher Packaging GmbH in its quest for more environmentally friendly and effective board production by improving the air system and the dryer section hood of the BM 1 in Schwarzenberg, Germany. “One year after rebuilding the ventilation technology by Voith, we can draw an all-round positive balance. Our hood is now closed completely and in combination with a larger heat recovery we need noticeably less energy,” says Matthias Reh, plant manager at Schumacher Packaging. “We were also able to increase production.”

On this project, Voith’s long-standing experience in the area of board and packaging paper machines again showed through. In several finely coordinated steps, Voith optimized the dryer section hood, the air system and heat recovery. The energy requirement was always the focus of the measures. Thus, the power requirement for driving the ventilation systems could be decreased significantly. The increase in efficiency met the high expectations of Schumacher Packaging. It allows the board manufacturer to produce its high-quality products in an even more sustainable fashion.

Schwarzenberg BM 1 has a wire width of 2,160 mm and an operating speed of 42 m/min to 133 m/min. It produces gray, brown and white solid board in a basis weight range of 350 g/m² – 1,050 g/m².

Schumacher Packaging is an owner-managed pan-European specialist for packaging made of corrugated cardboard and solid board. Founded in 1948, today the company employs more than 2,200 workers at 10 locations in Germany and Poland.

Voith’s new InForce polyurethane roll cover features high stability providing additional void volume with particularly deep and wide grooves for highly loaded positions. This additional benefit will not compromise the wear and abrasion resistance resulting into consistent dewatering during its complete operating cycle.

The strong material used in InForce means that the grooves exhibit virtually no deformation over time. The roll cover easily withstands extreme nip loads. As a result, the void volume remains constantly high over the entire lifecycle and ensures very good, consistent dewatering throughout.

InForce is the successor of Voith’s successful G2000 roll cover and available in two hardness levels. The structure ensures high stability. The WebNet layer located between the polyurethane and base layer has a three-dimensional polymer matrix specially developed by Voith which can withstand high temperatures and mechanical and chemical loads and therefore offers maximum operating reliability.

Especially in highly loaded presses steel grooves are often the preferred choice. The hard nip that occurs when using steel rolls impairs the lifecycle of the fabric and can also cause quality issues with the paper. The stability of InForce withstands the high loads while still providing the benefits of a polyurethane cover: surfaces can be tailored to the application, fabrics are not impaired in comparison with steel grooves.

Voith has brought a new IPV Rotor for virgin pulp onto the market. The new component has already proven itself for some months under mill conditions and shows its strengths here: energy consumption of the new rotor can be up to 30 per cent less than that of conventional technologies. This also enables energy costs to be lowered by up to 30,000 euros annually.

The IPV Rotor is part of the LowEnergy rotor family and was developed for application in the IntensaPulper (IP) by Voith as well as a retrofit component for existing Voith pulper and third party systems for processing virgin pulp (V). But the rotor can also be used to slush other clean raw materials like broke or fresh fiber.

The substantial reduction in energy consumption of up to 30 per cent is achieved by an innovative design that improves the flow characteristics inside the pulper. In addition, the pulping process can be further improved through integration of a so-called bale breaker. The bale breaker loosens the hard-pressed pulp bales before the actual dissolution in the pulper and thus disburdens the rotor, which has a further positive effect on energy consumption.

In practice, the new rotor has already proven itself in the IntensaPulper and in rebuilt pulpers of various paper manufacturers where they are delivering convincing results there. In the installations operating in the market, energy reductions range up to 4 kWh/t, depending on the raw material in use. This translates into savings in energy costs of up to 30,000 euros annually and the investment pays for itself within a very short period of time.

With Jade from the CleanWeave product line, Voith is bringing innovative dryer fabrics onto the market that translate reduced contamination to increased drying capacity due to their special design.

Jade dryer fabrics have minimal internal void volume and so carry significantly fewer deposits than conventional dryer fabrics. The high number of contact points and the flat yarns facilitate effective heat transfer and paper sheet handling. The compactness of the fabric structure makes both manual cleaning as well as on-line cleaning systems such as DuoCleaner Express from Voith more effective.

The SynStron yarn material used in Jade makes the dryer fabric especially effective in resisting fibrilation and so facilitates easy cleaning. Synstron is used in the entire CleanWeave product line and is noticeably more effective than conventional polyester yarns in resisting abrasion.

Jade^High expands the product line with a more open surface ensuring stronger air flows for increased evaporation. Like all dryer fabrics in the CleanWeave product line, Jade and Jade^High show measurable differences in their ability to maintain an easy clean structure which contribute to a more efficient drying process.

Through constant innovations, Voith Paper is optimizing the paper manufacturing process, focusing on developing resource-saving products to reduce the use of energy, water, and fibers. Furthermore, Voith Paper offers a broad service portfolio for all sections of the paper manufacturing process.

Voith sets standards in the markets energy, oil & gas, paper, raw materials and transport & automotive. Founded in 1867, Voith employs more than 43,000 people, generates € 5.7 billion in sales, operates in about 50 countries around the world and is today one of the biggest family-owned companies in Europe.

Voith Gecko OneStep is a unique system for start and end gluing on the winder. 16 gluing machines, with a Voith VariFlex winder using two-drum technology, have been sold in the past three years and also been successfully used in several rebuilds. Along with start and end gluing, Gecko OneStep also provides for perforation of the paper web.

The lizard family of geckos was the inspiration in naming the Voith Gecko OneStep, and for a good reason. Lizards’ feet have tremendous adhesive power and even allow the animals to hang upside down on glass panes. The performance features of Gecko OneStep are also unique; they ensure that the paper web adheres to the core.

Exact and quick functioning. When a new set is to be wound in the winder, both end gluing of the cut finished reels as well as the initial gluing of the paper web have to take place on the new core. With Gecko OneStep, preparation of start and end gluing is done at full machine speed, which minimizes time and production losses. The gluing machine is attractive due to its reliable handling and its exact and quick functioning. If a reel change is imminent, hot glue is applied with a low-maintenance nozzle on an anti-adhesive-coated transfer roll. The perforation knives for cross-cutting the paper web are on this transfer roll between the glue traces. The roll turns during a reel change. A glue trace is applied as end gluing on the paper web of the finished reel. Then perforation takes place, which later allows separation of the paper web. With the exactly positioned glue traces, the paper web then adheres to the core. The rugged and universal set-up means Gecko OneStep has a broad range of application, from thin paper of less than 30 g/m² all the way to board and packaging paper of over 440 g/m².

New generation of glues is double strength. Together with an optimized coating of the applicator roll, a newly developed generation of glues now provides for even better durability of the end sheet gluing. The strength of the gluing has been doubled, which improves both the storability as well as the transportability of the paper rolls. The optimized coating on the transfer rolls also has another positive effect: its service life has been tripled.

With Gecko OneStep, paper manufacturers can rely on a proven system that was developed with a high degree of technological know-how. Durable and resilient adhesion is ensured using only small amounts of glue which is also suitable for indirect contact with food. Together with VariFlex winders, Gecko OneStep offers a reliable system for the highest productivity.//

Voith has successfully completed the modernization of the pulp drying machine (PDM) at BSC – Bahia Specialty Cellulose, located in Camaçari, state of Bahia (Brazil). Voith’s solutions were installed in mid-March, during a total machine turnaround that lasted seven days.

The main goal of the modernization was to improve quality and increase the value added to BSC's acetate cellulose. Voith's technical team installed a new shoe press with tilt control and other equipment to upgrade various systems at BSC.

For BSC, the main benefit of the modernization will be the improved pulp quality, which will enable the company to serve its existing customers better and to open up new markets. “Now BSC will be able to rely on a greater array of tools to adjust quality of the final product. And because Voith was able to install all of the required components during the total machine turnaround, the company's production was not affected. It was a great challenge, and we were able to complete it successfully", points out Leunis Teixeira Rocha, Project Manager at Voith Paper.

BSC – Bahia Specialty Cellulose

Bahia Specialty Cellulose is Latin America's only manufacturer of soluble pulp derived from eucalyptus wood, and currently ranks as a world-class player in its segment. The company basically manufactures two types of soluble pulp: the “rayon-grades” and the “specialty-grades”, the latter of which are converted in the food, cosmetics, cigarettes, pharmaceuticals and tires industries, to name a few. Of its total production, which in 2012 amounted to 435,000 metric tons, 97% were exported to countries in Asia, Europe and the US. The remaining produce is sold to Brazilian manufacturers.

Voith and Cheng Loong Corp. signed the tissue machine contract for Cheng Loong TM 16 on July 18, 2014 in Taipei, Taiwan. This order continues the successful partnership between the companies Cheng Loong and Voith.

The TM 16 will be installed in Chupei, Taiwan, and will start up in September, 2015. It is based on a VTM 3 tissue machine concept from Voith and the scope of supply contains the newest technology which consists of a single-layer MasterJet Pro T headbox and the NipcoFlex T shoe press for reduced energy consumption. Furthermore, an 18-foot steel Yankee cylinder for best heat transfer and thus optimum thermal drying efficiency as well as a high-performance steam hood and the MasterReel reel belong to the scope of supply. Also included in the delivery are forming and press fabrics.

TM 16 will produce high-quality dry crepe toilet paper and hand towel with a wire width of 3,796 mm and a design speed of 2,200 m/min. As technology leader, Voith focuses on less energy consumption, less fiber usage and more flexibility in operation to fulfill industry demands. With the signing of this contract with Cheng Loong, Voith will strengthen its leading position in innovative technologies for the tissue industry.

Cheng Loong Corp. was established in 1959 and is an international paper making and service group with its footprint in China, Vietnam, Japan, USA and in the rest of the world. The annual production capacity is 2.2 million metric tons of paper and paperboard. Cheng Loong Corp. is ranked among the top 100 paper companies in the world.

Following a rebuild by Voith, the PM 2 of the Europac Group (Papeles y Cartones de Europa, S.A.) was successfully restarted at its plant in Duen͂as in the Spanish Province of Palencia after just 15 days of downtime and seven days of commissioning. This meant that the machine was back in production one day sooner than planned.

“In Voith we had a reliable partner at our side during this project. The entire rebuild was done in a very short time frame,” confirms Maria Berzosa, who is responsible for the project at Europac in Dueñas and continues: “Very quickly, the PM 2 was producing again top-quality packaging paper.”

The Europac Group had opted for a rebuild in order to produce also white coated testliner in the future. This was achieved by installing a Voith SpeedSizer, which applies a uniform, flawless film for sizing and coating, and systematically improves paper characteristics, penetration and surface coverage.

Europac chose to work with Voith because it has decades of experience and expertise in board and packaging paper machines. The SpeedSizer applicator unit supplied is one of many components from the Voith product range that has long-standing proven reliability. Europac could therefore be confident of making a reliable investment.

As well as the SpeedSizer, the scope of supply included a starch and coating colour preparation unit and a CB-Turn for non-contact turning of the paper web. The PM 2 has a production capacity of 150,000 metric tons per year of brown, white and white coated testliner at an operating speed of 1,100 m/min.

Europac Papel Duen͂as is part of the Europac Group (Papeles y Cartones de Europa, S.A.) which operates in the entire supply chain of the paper and packaging industry.

The newly developed Kinetic hybrid press felt from Voith differs from conventional press felts through its combination of a woven base structure and a non-woven yarn structure. Its modular design gives paper manufacturers the possibility of fulfilling their requirements for dewatering performance and sheet quality at the same time.

The non-woven yarn structure of Kinetic can be positioned both in machine as well as in cross direction and is designed for fineness and accuracy. Thanks to this structure, Kinetic has a large number of contact points, which provides for up to 20% more efficient dewatering of the paper web. The woven base structure can consist of up to threelayers depending on the water volume of the paper machine. Their composition facilitates stability and long running times. The combination of both concepts unites endurance and precision.

This hybrid structure offers better visual paper characteristics and accelerated start-up times. The cross profile of the paper web is also improved. Kinetic has almost no tendency to markings, compacting or contamination and thus increases the entire operative performance. Quicker start-up times, an extended service life and improved surface characteristics of the paper make Kinetic clearly more economical and thus more efficient than conventional woven or non-woven press felts.
