Rolls

Paper and board machine rolls

Maximum performance with high-quality rolls

With over 50 years of roll manufacturing experience, innovative R&D, and the process know-how of a paper-machine builder, Valmet offers highly reliable roll solutions that provide maximum performance and extend maintenance intervals.

Valmet's rolls are made in modern roll workshops, each specializing in a given roll type. Our manufacturing processes meet all the tolerance and quality requirements of each application. The latest manufacturing technology and strict tolerances result in high-quality products with excellent operating performance, low vibration levels, and fewer sheet breaks.

The long operational life of new rolls is ensured by accurate dimensioning, durable materials, and functional roll design. With decades of experience, we have access to a vast library of original roll manufacturing drawings, which are used to engineer fully compatible spare rolls for all applications, regardless of the original machine supplier.
