SHOE PRESS FOR THE DEWATERING OF A FIBER WEB ABSTRACT OF THE DISCLOSURE A shoe press having a press nip which is lengthened in direction of travel of the web passing through the nip. The nip is forms by a press shoe having a concave slide surface over which there slides an endless press belt which can be pressed against a backing roll by means of the press shoe. The press shoe is guided in the pressing direction within a pressure space which is provided in a stationary support member. The center axes of the backing roll and the annular, stationary support member lie in a press plane E. The slide surface of the press shoe is divided by the press plane into a web nip entrance zone and a departure zone. The length of the entrance zone is greater than the length of the departure zone by at least a minimum ratio. A porous belt press wire passes through the press nip between the web and the press belt. The porous belt has a denser cloth layer toward the web and less dense cloth layer away from the web. The surface of the press toward the porous belt is smooth and there are reinforcements in that press belt away from that smooth surface. SPEC\19871
