Method in the coating of a roll of a paper machine and a coated roll of a paper machine

摘要

The invention concerns a method in the coating of a roll (T) of a paper machine, which roll (T) is coated with a polymer, preferably with polyurethane. In the method, the desired surface property values of the roll are fed into the central unit (10) of the system. In the method, the roll is coated while following a function f₁(x),f₃(x) that has been created in the central unit (10) over the distance of the length of the roll, whereby a surface hardness or surface profile corresponding to the formed function f₁(x),f₂(x) and comprising no steps or other points of discontinuity can be formed. The invention also concerns a coated roll of a paper machine.
