ABSTRACT:
A press roll for a paper machine includes a cylindrical mantle formed of metal providing the roll with mechanical strength. A coating is provided on the roll mantle, the coating being partially or entirely metallic. The metallic coating is preferably formed of stainless steel containing chromium and provides for a controlled detachment of the paper web from the roll coating as well as durability, i.e., ability to withstand various strains to which the roll surface is subjected. In addition to the metallic component, the roll coating may also include a component or components of ceramic material.
