摘要：
A web (W) passes through a press section having two separate press nips (N1, N2). At least the first press nip (N1) has two water-receiving press felts (31, 41). After the first nip (N1), the web (W) is separated from one press felt (31/41) and transferred on support of the opposite press felt (41/31) through the second press nip (N2). One roll of the first nip (N1) is a press suction roll (11, 110) and the web (W) is transferred to follow the press felt (31, 41) on the side of said press suction roll (11, 110) by means of an underpressure in a suction zone (11a, 110a) of said press suction roll (11, 110). The press felt (31, 41) on the side of the press suction roll (11, 110) is also passed through the second nip (N2) of the press section.
