Abstract

A hydraulically supported roll includes a stationary crosshead extending through a rotatable hollow roll, which is heated at its inner and outer circumferences. A thermostatic control and regulating device is provided to keep the temperatures at the inner circumference and the outer circumference of the hollow roll at the same level during the heatin-up and/or cooling-down phase.
