VoithPaper, Germany, has launched the NanoPro roll cover for calenders. The new roll cover provides a noticeable reduction of vibrations, the company notes. It is available for supercalenders, soft calenders, and multi-nip calenders.
The vibration resistant NanoPro cover provides reliable and consistent performance due to its unique attributes in areas where vibrations would normally restrict the performance of roll covers. In comparison with other conventional roll covers, it manages to further reduce vibrations, even under difficult conditions. Annual operating and maintenance costs are thus lowered. Also, the profile of NanoPro remains uniform due to its high level of wear and abrasion resistance, Voith emphasizes.
The multi-layer fiber-reinforced roll cover guarantees a uniform distribution of nanoparticles, Voith says. Customized components and the manufacturing process ensure that the NanoPro layers can withstand severe impact damages. NanoPro also distributes high compressive stresses evenly over the entire nip, providing the best possible sheet characteristics for gloss and smoothness and ultimate running behavior.
