Abstract (en)

[origin: WO9916967A1] A method of supporting a press shoe in a shoe press for a paper of board machine, said press shoe (2) forming together with a counter roll (12) an extended nip (N) for a paper or cardboard web (W) and for a flexible circulated belt (12). On the outside of the loading cylinder (3, 4) of the press shoe there is arranged a compartment (15), to which hydraulic fluid is supplied in such a maner that the hydraulic fluid in the compartment directly or indirectly exerts a force upon the press shoe in the direction opposite to that of the force exerted upon the press shoe by the loading cylinder. The cylinder part (4) of the loading cylinder is movably arranged on the piston part (3). Said forces are dimensioned such that in operation they create a gap (16) between the press shoe and the loading cylinder, or between the supporting beam (9) of the press shoe and the loading cylinder, thereby allowing hydraulic fluid to flow out of the compartment (15). In an embodiment of a shoe press as described above, the working chamber (5) of the loading cylinder (3, 4) can communicate with the compartment (15) via a throttle (14). Alternatively, the working chamber and the compartment can be supplied with hydraulic fluid independently of each other.
