Abstract
A heatable roller which can be heated from inside the roller body by a heating device. Provided radially outside the heating device are axially parallel bore holes uniformly distributed over the periphery of the roller body which are connected at the ends by annular chambers. The bore holes and the annular chambers form a closed system which is partially filled with water. This system operates to make the temperature uniform via condensation heating in the event of local temperature reduction.
