Roll covers for pulp drying

Valmet’s advanced material technology and expertise provide optimal roll covers and coatings for all positions in pulp drying machines. As an industry leader, we are able to offer a broad range of materials and solutions for varying needs. Our aim is not just to meet our customers’ requirements, but to offer added value and expertise that moves the mill’s pulp drying performance forward.

Modern roll cover materials bring more benefits

In many cases, traditional rubber covers no longer provide optimal wear resistance and can often be replaced with a more modern material, such as composite or polyurethane covers. Compared to custom rubber, these modern roll cover materials bring clear, long-term benefits in reduced maintenance intervals and improved dewatering. 

Our online roll cover tool makes browsing through Valmet’s roll covers and coatings easier than ever. You can find roll covers such as rubber cover Lead Roll Cover GM with improved wear resistance, Press Roll Cover VT, a tough composite cover that provides longer cover life, and hard coating Press Roll Cover TM for the most demanding conditions.

The tool also helps you choose the ideal roll cover for any roll position in a pulp drying production line. All roll covers and coatings for pulp drying can be found in one user-friendly view, along with their technical data.


iRoll Tension unlocks hidden potential in pulp drying

One exemplary innovation in our roll cover technology is iRoll Tension, an online tension measurement tool designed to measure tension profiles and quality online without any speed or web property restrictions. It is an excellent tool for improving paper and board machine runnability, and it can be utilized in improving end product quality, even in pulp drying.

Roll covers from recyclable and renewable raw materials

Could paper machine roll covers be made of recycled or even bio-based raw materials? After less than two years’ intensive R&D work, Valmet has introduced new composite covers for press, guide and calender rolls representing a new, more sustainable generation of roll cover materials.
