Aggressive chemicals can quickly damage a polyurethane roll cover and lead to increased surface wear. SupremePress has been specially developed for press roll positions that are exposed to high levels of chemical attack. The innovative polyurethane cover has excellent chemical resistance and improved hydrolysis resistance for longer cover life and constant drainage.

ArcticPress for press rolls and ArcticFlow for suction rolls were especially developed for medium speed applications. The roll covers integrate the latest polyurethane materials for best impact and abrasion resistance for long grinding intervals with constant profile, press nip and dewatering conditions. Both roll covers have a unique cover build-up with a thicker functional layer for more lifetime.

ArcticSoft is a roll cover made from polyurethane with an innovative structure for pressure rolls and suction press rolls in tissue machines. With the new mini base layer, the functional layer can be increased, resulting in even longer service life. The polyurethane functional layer combines hardness stability, wear resistance and elasticity. The proven surface design ensures optimal drainage. ArcticSoft is suitable for all tissue applications with medium high speeds and can withstand the harsh environment of a press section.
 

The innovative coater backing roll cover is specially made for high-demand positions in blade coater applications.

• Meets the requirements of stable profile conditions and highest wear resistance

• Made with a new polyurethane chemistry and unique filler concept

Withstands chemical attacks longer than any other polyurethane cover
SupremeFlow represents a continuous progression that started with the development and market introduction of IntenseFlow, a proven cover for the pulp industry. SupremeFlow now offers the outstanding chemical resistance needed for graphic and board & packaging machines.

“The new suction press roll cover SupremeFlow from Voith is the ideal product for optimizing our machine performance at the Frantschach site. With the polyurethane cover, we were able to triple the service life compared to the previous product. In addition, we were able to achieve a positive effect on the cover with the changes to the press hydraulics. As a result, we are more than convinced of the overall performance of the SupremeFlow.”

• Damage resistance 
• Hydrolysis stability

The high-performance polyurethane roll cover SupremeFilm completes our film press portfolio. In addition to UniFilm and eVenFilm, our customers can now select this premium roll cover as well. The outstanding properties of polyurethane have been used for many years for high-end press section solutions and have now been tailored to the needs of film presses.

“SupremeFilm allowed us to keep the two Sigma profiles constant over an unprecedented installation period. This has achieved our ultimate goal of producing perfect paper quality.”
Dietmar Muser, Manager Paper Mill, Sappi Ehingen GmbH

In addition to exceptional wear resistance, state-of-the-art AiroGuide C guide roll covers offer exceptional quality and performance, less downtime and greater cost savings:

• Best material at low investment costs

• Long service life and reduced maintenance costs thanks to wear and temperature-resistant materials

• Smooth surface and low contamination

• No corrosion problems

• One expert for all guide roll covers

• Increased performance level by combining AiroGuide C with tailored fabrics and doctor blades

TerraSpeed Supreme was specifically designed for board, packaging and specialty applications. Due to the used raw material qualities and chemical additives for better sheet release, the requirements of roll covers are especially high in those applications.

With this roll cover for coater backing rolls, Voith is adding a highly durable option to its portfolio of coater roll covers that need less regrinding and therefore reduce shutdown and maintenance costs.

EvoStretch is a spreader roll designed by Voith experts. Benefit from its reliability due to latest Voith technology and the extensive service know-how. Within a short service time, conventional spreader rolls can be upgraded by adding our exclusive EvoStretch Bearing with selfhealing function and the high-performance polyurethane sleeve SolarStretch.

The German paper manufacturer Koehler Paper produces specialty papers at five production sites using state-of-the-art technology. In particular, the production of SD and thermal papers at PM 1 at the Kehl site is demanding, as special fillers and auxiliary materials, such as PCC, AKD, and coated broke are used here. Due to the technological challenges, Koehler Kehl decided at the beginning of 2019 to switch roll covers from competitors to the newly developed Voith roll cover TerraSpeed Supreme.

Hamburger Containerboard, a producer of high-quality corrugated case material products for customers throughout Europe, has significantly reduced cleaning efforts during shutdowns and increased efficiency thanks to Voith's new thermal protection coating TerraDry PN.

A Southern U.S. tissue mill, which produces virgin and recycled fiber products for both the consumer and commercial markets, recently expanded its relationship with Voith as the company proved its service excellence and quality product offerings.

A Midwestern U.S. tissue mill, which produces light, dry crepe tissue on a traditional crescent-forming machine, recently expanded its relationship with Voith as the company proved its service excellence and quality product offerings.

A board mill in the eastern United States was experiencing chemical degradation issues on its suction press roll cover. The MegaFlow cover from Voith solved these problems and showed a uniform profile from edge to edge over the front face of the roll, a greatly reduced cupping of the suction holes and no sheet marking.

The upgraded presses allowed for a boost in the solids coming out of the press section. Solids increased from 43 percent before the rebuild to 49 percent after the rebuild. Voith exceeded 100 percent of the project goal and was awarded credit for the project’s success. The machine set new all-time production records shortly after starting up from the rebuild.
