Rubber roll covers for tissue

Improved polymer matrix leads to reliable tissue production


To ensure especially long-lasting and efficient operation, Voith has now launched its newly developed MajorSoft and MegaSoft rubber roll covers for tissue production. The distinctive feature of these roll covers is their improved multilayer structure. Due to various improvements in production, the bonding force between the individual cover layers is four times as strong as with conventional rubber roll covers. MajorSoft is very long-lasting and durable and at the same time it improves production efficiency. MegaSoft has an innovative functional layer that consists of a special rubber polymer matrix characterized through better wear resistance and mechanical strength. Grooves and open surfaces of up to 35% are now possible. Re-hardening is reduced, the void volume is increased and there are less material deformations.

In test runs a tissue machine achieved a production speed increase of 25 m/min, dry content was 1.2% higher and total production increased by 1.3%, all thanks to MegaSoft. The tissue manufacturer can save nearly 180,000 euros annually by using MegaSoft.
