摘要

Frame construction for the press section of a paper machine, in which said press section there are two or three subsequent and separate press nips (N1,N2,N3) substantially dewatering the web (W). The nips are formed between two opposite press elements, such as press rolls. Through the nips the web (W) runs as supported by a dewatering and/or transfer fabric. The frame construction of the press section comprises a front frame (110) and a rear frame (130) separate from each other, between which a space (T) open at the top is provided. This space (T) is arranged so as to be utilized in the replacement of both the upper press and/or transfer fabrics (20,30,31) and of the press rolls. At least the upper roll (24,34) of the first or second nip (N1,N2) is attached in connection with the rear part of the front frame (110). At least the upper roll (34,54) of the second or third press nip (N2,N3) is fitted in connection with the front part of the rear frame (130).
