A device for influencing a roll temperature via at least one fluid flow, which is separate from the pressure fluid is also included. The support elements are arranged into a plurality of controllable roll zones arranged along the roll axis. The temperature influencing device is structured and arranged to locally charge respective roll zones depending upon a pressure on the support elements in a respective roll zone.
