Abstract

Press section of a machine for manufacturing a fibrous pulp web. The press section may include a press roll, at least one flexible circulating press belt, at least one press shoe, and at least one extended press nip formed to extend in a web run direction by the press shoe pressing the flexible circulating press belt against the press roll. The press section further includes one of a felt or screen belt that may be guided through the at least one extended nip, and the press roll may be substantially centrally located within the press section and may have a diameter greater than a diameter of the at least one flexible circulating press belt. The center press roll has two press shoes positioned opposite it; the two press shoes are offset with respect to one another such that the direction of force exerted by each extends through the center press roll axis and defines an acute angle, with support elements within the center press roll positioned opposite the press shoes.
