Abstract

A nip is formed between a backing roll (10) and a loading roll (20). The loading roll (20) is comprised of a stationary support structure (21) and, adapted to run about the same, a flexible mantle (22) supported by its inner surface (22a) on said support structure (21) by means of at least one supporting member (23) serving to press said flexible mantle (22) against said backing roll (10). The loading roll (20) includes further at least one essentially axially aligned row of discrete pressure medium feed points (25, 26), whereby a pressure and/or flow rate controlled flow of pressure medium can be fed through the feed points (25, 26) of said at least one row against said inner surface (22a) of said mantle (22). According to the method, the pressure medium fed through said feed points (26) is used cross-machine direction (CD) profiling of the paper or board web passing through the nip (N).
