Abstract

A fibre web is supported by a fabric or between two fabrics and passes through a press nip formed by two press rollers to be dewatered by pressing. An elastic compression mat or plurality of mats thicker than the fabrics also pass through the press nip. The material and/or structure of the mat or mats is selected so that, based on the phenomenon of hysteresis, a retardation is obtained for the restoration of the thickness of the mat, occurring after the median line of the nip, such that the compression pressure in the nip is reduced relatively steeply, as compared with a symmetric distribution of the nip pressure, and due to the retardation the fabric or fabrics may be separated very soon after the median line of the nip, so that rewetting of the web is reduced.
