Abstract
A roll (20) comprises a rotating hollow roll (1) and a stationary crosspiece (5) which extends through the hollow roll (1) lengthwise and the ends of which protrude from the hollow roll (1) and are supported there. The crosspiece (5) comprises a support shoe (10) which is closed against a supporting part (6) of the crosspiece (5) except for feedlines, which is held at the crosspiece (5) in the circumferential direction but is movably guided in the action plane (9) of the roll (20) against the inside circumference (4) of the hollow roll (1) and can be pressed against the inside circumference (4) of the hollow roll (1) under the pressure of the pressure liquid. On the side facing the inside circumference (4) of the hollow roll (1), the support shoe (10) carries longitudinal seals (7) and guiding surfaces (12) which divide off a longitudinal chamber (8) for receiving pressure liquid generating the line pressure, and leakage chambers (15) for receiving leakage liquid.
