Customer case:

Increased roll lifetime with Valmet Press Roll Cover PL-V

Jan 30, 2025

A tissue producer in Southeast Asia faced challenges in increasing the lifetime of their suction touch roll cover. Initially, the customer was using a blind-drilled rubber cover. To enhance roll performance, extend its lifespan, and ensure excellent end product quality, a new solution was required.

Increased roll lifetime with Valmet Press Roll Cover PL-V

We are highly satisfied with the Valmet Press Roll Cover PL-V. The new PU cover has extended the suction touch roll's lifetime from 2 to 5 years. This improvement has not only reduced our maintenance costs but also ensured consistent, high-quality end products. As a result, we have placed three repeated orders."

Press roll covers

In tissue machines, pressing is a very brief and compact yet vital process for effective water removal. It thus places great demands on the durability, maintenance costs and energy consumption of the roll covers in the press section.
