Abstract
A roll for a pulp machine, paper machine, or paper finishing machine with a cylinder mantle of cast iron or steel, or any other equivalent metal, which bears the mechanical loads. On the roll mantle, fixed to the outer face of the mantle, there is a resilient polymer coating, and onto the polymer coating a coating is fixed which is by several orders thinner than the radial thickness of the polymer coating. This coating fixed onto the outer face of the polymer coating is a metal, ceramic, cermet or plastic coating.
