Abstract
A controlled deflection roll is disclosed comprising a stationary support and a rotatable hydraulically supported roll shell. There is also provided heating of the hydraulic liquid which is infed to the controlled deflection roll by a pump device. The pressure line of the pump device is connected by means of a heat exchanger with a return flow line. Connected after the heat exchanger is a cooling device having a temperature regulator. In the pressure line there is arranged following the heat exchanger a heating device. The return flow line is connected by means of an overflow valve with a container for hydraulic medium which is fed to a heating device for the controlled deflection roll.
