Abstract

In a shoe type press used in a wet press for the dewatering of a fibrous web (W), the press shoe (2) is exposed to forces tending to bend the shoe (2) in a plane substantially parallel to the direction of the movement of the web (W) through the extended nip. According to the invention, means (12) are provided for at least substantially outbalancing such forces. These means (12) may include means (13) for sensing a difference in temperature between the leading edge (8, temperature TA) and the trailing edge (9, temperature TB) of the shoe (2), and means (14) for cooling the trailing edge (9) and/or means (20) for heating the leading edge (8), so as to minimize the temperature difference (TB - TA). The cooling and/or the heating may be carried out be providing a conduit (18 and 21) in the respective edge (9 and 8) and passing a cooling or a heating agent, respectively, through the conduit in heat exchanging relationship with the shoe (2).
