Estimating the term…
A separation process including providing a flexible belt photoreceptor comprising a photoconductive layer on the outer surface of a flexible metal belt substrate, the photoconductive layer including amorphous selenium or selenium alloy, transporting the substrate through an arcuate path having a small radius of curvature to apply stress to the photoconductive layer, and abrasively removing substantially all of the selenium or selenium alloy remaining on the substrate. This process may be carried out in an apparatus which includes at least one member having an arcuate surface with a small radius of curvature, means to transport the belt photoreceptor in an arcuate path over the arcuate surface, and abrasive means adapted to to contact and remove substantially all of the photoconductive layer from the substrate.
A process for removing a photoconductive layer from a substrate comprising providing a flexible belt photoreceptor comprising a photoconductive layer on the outer surface of a flexible metal belt substrate, said photoconductive layer comprising a selenium composition selected from the group consisting of amorphous selenium and selenium alloy, heating said belt photoreceptor until said photoconductive layer forms blisters on said flexible metal belt substrate, transporting said substrate through an arcuate path having a small radius of curvature to apply stress to said photoconductive layer, and abrasively removing substantially all of said selenium composition remaining on said substrate.
