ABSTRACT:
A coated roll and a method for coating a roll used in a paper machine. Desired surface property values of the roll are fed into a central unit of the coating system and the roll is coated while following a function f.sub.1 (x),f.sub.3 (x) created in the central unit over the distance of the length of the roll. A surface hardness and/or surface profile corresponding to the formed function f.sub.1 (x),f.sub.2 (x) is derived which does not have any steps or other points of discontinuity. The roll is coated with a polymer, preferably polyurethane.
