Abstract
A calender bowl comprises a central elongate shaft having a flange at each end thereof. This arrangement defines a region which is filled with a filler material. The region to be filled with the filler material is the annular area around the shaft and it is filled by transversely threading numerous disc-shaped sheets of fibre and possibly conducting discs, thereon. Copper rods are disposed within the filler, along all or part of the length of the calender bowl, and lie in thermal contact with the flanges to help dissipate heat.
