ABSTRACT:
The invention concerns a roll or cylinder or roll coating for a pulp machine, paper machine, or paper finishing machine, in which application the roll or equivalent comprises a cylinder mantle of cast iron or steel or any other, equivalent metal, which bears the mechanical loads. On the rollor cylinder mantle, fixed to the outer face of the frame mantle, there is a resilient polymer coating, and onto said polymer coating a coating is fixed which is by several orders thinner than the radial thickness of the polymer coating. Said coating fixed onto the outer face of the polymer coating is a metal, ceramic, or cermet coating or a plastic coating. The invention further concerns a method for the manufacture of a roll coating in accordance with the invention as well as the use of such rolls and coatings.
