Roll types

Full range of roll products for paper industry needs

Suction rolls

Suction rolls provide high performance on all types of machines from low-speed pulp drying lines to the latest paper, board and tissue machines designed for operating speeds in excess of 2,000 m/min (6,560 ft/min). Aside from rolls for Valmet machinery, we can also offer appropriate spare rolls for a number of other makes. Many of our latest roll technology innovations can be adapted into spare rolls that are compatible with existing rolls. This is an easy and cost-effective way to improve suction roll performance.
