摘要

The roller arrangement (10) has three rollers and two roller pairs, between which two press nips (N1,N2) are formed, through which the fibrous sheet material is controlled. Each roller pair has a roller (1) with fixed axle and a roller shell (1c,3c) rotating around this axle. The central axle of the support elements of the roller stressing the region of the former press nips progress in the machine transverse direction at the axle (1b,3b) of the roller and the central axle of the support elements of the roller stressing the region of the later press nips.
