<p>The invention concerns a press section in a paper machine, through which press section the paper web (W) has a closed and supported draw. The press section comprises at least two successive separate press nips (NP1,NP2,N3; NP3), dewatering of the paper web (W) being carried out at least in the first one of said press nips, preferably between two press fabrics (20,30) that receive water. The last press nip (N3;NP3) in the press section is an equalizing press nip (N3;NP3), which is separate from the preceding nip (NP2) and in which no substantial dewatering is performed. The paper web (W) is passed through the equalizing press nip (N3;NP3) from the preceding dewatering press nip (NP2) on a transfer belt (50) substantially not receiving water, on its substantially straight run. This run is continued after the equalizing nip (N3,NP3) as a run (50a) of substantially the same direction, on which run, by means of the difference in speed of the transfer belt (50), if necessary, some of the elongation of the paper web (W) in the machine direction is compensated for, which elongation takes place in the equalizing nip (N3,NP3). <IMAGE></p> |
