Roll covers for every application
The Roll Cover Technology
Roll cover technology is a key factor in improving sheet release, reducing draw, improving dewatering performance, ensuring consistent coating and sizing, and achieving excellent calendering results. The various applications on the paper machine require a variety of roll cover designs and coating materials.
Materials range from ceramic coatings to very soft elastomeric covers

New Ceramic Roll Cover: TerraSpeed Supreme
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.
Our customers are excited about this new cover:
Since we have been using the new TerraSpeed Supreme from Voith Paper operation has been absolutely reliable at this critical position. In combination with Voith's SkyTerra S doctor blades, we have now been operating the unit for more than 2 years without interruptions and there has been no need to re-machine the roll surface. Web breaks originating from the Nipco-P roll have dropped significantly, sheet passing does not occur anymore and performance has been very stable over the entire operating time. The newly developed ceramic-coating TerraSpeed Supreme from Voith Paper has significantly improved our production but above all has made it operationally reliable again.
All these problems have been solved since we started using TerraSpeed Supreme from Voith Paper. In combination with the Voith doctor blades SkyTerra and SkyTop, the cover service lives could be substantially increased. There is no more sheet passing and web draws could be reduced. The newly developed ceramic cover TerraSpeed Supreme from Voith has considerably simplified our production.
