A press apparatus for dewatering a pulp web has two press rolls (14, 16) that form a press nip (12). The first press roll (14) is retained in the axial direction at least at one end, and is held with its bearing pins (53) on first bearing blocks (19). The second press roll (16) is also held with its bearing pins (55) on second bearing blocks (21a) . The second bearing blocks (21a) can be tensioned, each in pairs, with respect to the first bearing blocks (19) by means of flexurally elastic tension elements (26), the tension elements (26) allowing a relative displacement of the press rolls (14, 16) in the axial direction. The second bearing blocks (21a) are fixed in position with respect to the first bearing blocks (19) in order to prevent excessive bending stress on the tension elements (26) . For this purpose, either the rotary bearings (25a) of the second press roll (16) are configured in non-tilting fashion, or additional support bearings (27a) are provided (Fig. 3). |
