ABSTRACT:
Press section for a paper machine and a frame construction for the same which comprises a front frame and a rear frame. Press rolls are mounted on the front and rear frames and form a press roll combination in which press fabric is passed through nips formed thereby. An at least partially open space is situated between the front and rear frames which are not directly connected to one another and above the press roll combination, through which at least most of the press rolls can be replaced. This space also facilitates replacement of upper press fabric. A suction roll is mounted in conjunction with a rear side of the front frame, while a hollow-faced press roll is mounted in conjunction with the front frame. A smooth-faced center roll of the press is mounted in conjunction with the rear frame or with a separate intermediate frame, preferably in conjunction with a projection part of the frame. This center roll forms a second nip in the press together with the hollow-faced press roll, in a running direction of a web therethrough.
