Abstract
The present invention is directed to a heated sag-compensation roller, with short heat-up and cool-down times and a more even temperature distribution, which reduces the risk of damage to the roller shell. These improvement are achieved by the roller shell being heated or cooled from the inside and the outside simultaneously. The heating devices can be controlled so that the temperature difference between the inside and outside does not exceed a particular value.
