Roll covers for tissue machines

Tissue roll covers

Valmet’s roll cover expertise is based on solid expertise in materials, roll technology and tissue-making processes. As a result, users can enjoy maximum performance in all processes that include roll covers. Our roll cover portfolio includes a wide range of high-tech solutions for tissue-making.  

At Valmet, we are constantly working to develop the essential press properties of a roll cover, such as durability, reliability and dewatering capability. Our comprehensive product offering of both polyurethane and rubber covers for press applications clearly demonstrates our successful results. 

Press roll covers, in particular, play a significant role in tissue machines. In tissue pressing, nip pressure profiles also often impose extra challenges on efficiency and product quality. Valmet’s iRoll technology offers excellent tools to measure, analyze and optimize nip pressure profiles in tissue machines. Optimizing roll cover material, hardness and topography, as well as combining it with an optimized nip pressure profile, will let tissue-makers benefit from the best tissue profiles, improved productivity and better energy efficiency.
