Abstract

A process for the removal of a seamless substrate from a casting mandrel onto a support mandrel to prevent or minimize defects is disclosed. The support mandrel is inserted into the casting mandrel after a polymeric substrate is prepared on the inside of the casting mandrel and before complete cool down and release of the polymeric substrate from the casting mandrel. A minimum spacing is maintained between the support and casting mandrels, and with cooling to room temperature the substrate becomes self releasing and transfers to the support mandrel. The support mandrel is removed from the casting mandrel and further coatings can be applied to the outside surface of the substrate. The diameter of the support mandrel allows a minimum spacing between the substrate and the support mandrel. The process maybe useful in fabricating seamless substrate photoreceptor belts for xerographic applications.
