ABSTRACT:
A method and apparatus for coating photoreceptors used in copying machines. Prior to coating, an elastically deformable material is placed about the external surface of a mandrel to accommodate the belt. The thickness of the material is such that when the belt is pushed over the mandrel the deformable material is deformed and engages the interior surfaces of the belt facing the mandrel. As a result of heating and cooling steps involved during the coating process, the belt contracts and expands differently than the mandrel. The deformable material deforms accordingly to maintain consistent contact throughout between it and the undersurface of the belt.
