摘要

Press section of a paper machine and a frame construction for same, which comprises a front frame (50) and a rear frame (60). On the front and rear frame (50,60), press rolls (41,13,15,20,31) are mounted, which form a press roll combination, in which there are press nips (N1,N2,N3) formed between press rolls, the press fabrics (10,30,40) being passed through the said nips. An at least partly open space (T) is placed between the front and rear frame (50,60), not directly connected to each other, and above the said press roll combination, through which said space at least most of the press rolls can be replaced. This space (T) also facilitates the replacement of the upper press fabrics (10,30) placed in its connection. A suction roll (13) is mounted in connection with the rear side of the front frame (50). A hollow-faced (15 min ) press roll (15) is mounted in connection with the front frame (50). A smooth-faced (20 min ) centre roll (20) of the press is mounted in connection with the rear frame (60) or with a separate intermediate frame, preferably in connection with a projection part (70) of same, which said roll (20) forms the second nip (N2) in the press together with the press roll (15).
