Electrically heated calanderroll

In order to be able to heat, without difficulty, using rod-shaped electric heating elements 5, a heatable calender roller 1 for processing web-like materials, such as paper, axially parallel channels 4 which are used for heating being situated beneath the peripheral surface of the roller body 2, the heating elements 5 are arranged in the channels 4 and, in order to obtain favourable heat transmission, the spaces between the inside surfaces of the channels and the casings of the heating elements are filled with a metal 6 and/or a metal alloy, the melting point of which is situated above the maximum surface temperature reached during operation by the heating element.
