Abstract

A roll with a revolving hollow roll and a stationary cross head which extends therethrough lengthwise, spaced a distance from the inside circumference of the hollow roll on all sides, has, in the space between the hollow roll and the cross head, a longitudinal chamber provided with a feed line for pressure liquid, divided by a sealing arrangement which comprises strip shaped longitudinal seals extending on both sides of the action plane of the roll, as well as transverse end seals. The transverse end seals are designed as gap seals, the gap surfaces of which are kept spaced from each other by separate precision antifriction bearings.
