ABSTRACT:
A calender roller includes a hollow cylindrical roller body which is traversed by a stationary shaft whose outer diameter is smaller than the inner width of the roller body so that a gap is defined therebetween. The opposing end portions of the shaft are provided with rolling bearings to support the roller body and accommodate the channel system for connecting the gap with an inlet and outlet for a thermal transmitting fluid. Provided between the lateral end faces of the gap and the bearings are sealing and fitting members which are movable in axial direction to control the length of the heating zone along the roller body.
