Forming roll covers for board and paper
Roll covers to protect against wear and corrosion
Valmet has a wide range of protective lead and drive roll covers for the forming section rolls of your board or paper machine. We have developed unsurpassed polymeric covers and hard coatings for different needs.
Long service life due to good wear and chemical resistance
Excellent corrosion resistance
Easy doctoring
Protection in harsh, abrasive and wet environment
The universal task for roll covers in the forming section is to maintain roll dimensions such as the roll diameter profile in CD, so that wires can be rotated and guided smoothly and gently in the rolls without slipping or other problems. Valmet lead roll covers protect rolls in harsh, abrasive and wet environment from wear and corrosion.

Roll cover requirements for tube and drive rolls
Roll cover materials such as ceramic coatings with extremely high wear and corrosion resistance are essential for the forming section. Besides steel tube rolls, stainless steel suction rolls and carbon fiber tube rolls can be coated with Valmet’s high-performance covers. Wire drive rolls need proper traction, and positions requiring the highest traction from the roll surface will need Valmet drive roll covers, which are durable soft rubber or polyurethane covers. Along with top-of-the-line roll covers, Valmet can support papermakers with other forming section services, such as optimal doctoring solutions.
