Abstract
A roller (100) for the pressure treatment of fabric webs includes a hollow cylinder (1), rotatable about its axis A and bearing the working roller periphery (4). A non-rotatable crosshead (5) extends through the hollow cylinder (1) along its length, leaving all around a distance with respect to the inner circumference (2) of the hollow cylinder (1). The cylinder (1) is supported at the ends on external support pieces. A support device (10) is arranged on the crosshead (5) and acts radially in the active plane (W) of the roller (100) against the inner circumference (2) of the hollow cylinder (1). The support device transmits from the crosshead (5) to the hollow cylinder (1) the forces that are necessary for creating the line forces exerted by the roller (100). Provided laterally on the crosshead (5) is a hydrostatic support element (30) acting radially perpendicular to the active plane (W) of the roller (100) against the inner circumference (2) of the hollow cylinder (1). The hydrostatic support element (30) is hydraulically extendable against the inner circumference (2) of the hollow cylinder (1) and has on the exterior side an arrangement of hydrostatic bearing pockets (60) that a…
