Abstract

In a spray-coating process for preparation of photosensitive belts a metallic or plastic liner or sleeve is used to support the substrate being sprayed. A problem arises in the heat drying stage wherein the substrate shrinks and it becomes exceedingly difficult to remove the substrate from the liner without damaging either. Release agents and air-floating liners have been used to overcome the problem but with limited success. Release agents contaminate the substrate and air-float liners tend to carve structurally weakening and uneven patterns into the backside of the substrate.
