Abstract

The roller exhibits a support body which is provided with a plurality of support disks. Insulating layers are arranged between the support disks. A heat-resistant cable surrounding the support body in several coils is embedded in each insulating layer. The insulating layer consists of fiber material which is sprayed on at the same time as the cable is wound around the support body. The cable provides a firm and lasting connection of the insulating layer to the support body.
