Abstract
A roller 1 which serves to press a copy sheet against a heating plate of a fixing device in an electrophotographic copier is equipped with a clinging plastic tape 3 wound spirally around the roller. The end portions 6,6' of the roller are provided with clamping means. The tape 3 has holes and pointed ends. The roller ends have different lengths, and over the longer roller end 10 a clamping sleeve 4 is slipped and is mounted on a shaft, thus forming the end portion 6'. The clamping sleeve has a tapped hole penetrating its wall and provided with a set screw which is screwed down to lock the clamping sleeve, which is otherwise rotatable about the shaft, in a position in which the tape is wound tightly around the roller surface.
