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).

Une presse de séchage de bandes de papier comprend deux rouleaux de compression (14, 16) qui forment une emprise de compression (12). Le premier rouleau de compression (14) est fixé dans le sens axial au moins à une extrémité et soutenu par ses tourillons (53) sur des premiers paliers (19). Le deuxième rouleau de compression (16) est soutenu lui aussi par ses tourillons (55) sur des deuxièmes paliers (21a). Les deuxièmes paliers (21) peuvent être serrés en paires par des éléments élastiques flexibles de traction (26) par rapport aux premiers paliers (19). Les éléments de traction (26) permettent un déplacement relatif des rouleaux de compression (14, 16) dans le sens axial. Les deuxièmes paliers (21a) sont fixés en position par rapport aux premiers paliers (19) afin d'éviter une sollicitation excessive à la flexion des éléments de traction (26). A cet effet, les paliers rotatifs (25a) du deuxième rouleau de compression (16) sont fixés de manière à ne pas basculer ou des paliers supplémentaires de support (27a) sont prévus.
