Abstract

Disclosed is a method for web coating of belted photoreceptor materials comprising embossing the edges of the web material in a precoating step by passing the web through a set of embossing wheels situated at the edges of the web so that, for example, a symmetrical raised pattern is imprinted onto the uncoated outer edges of the web. The embossed pattern is created so that alternating embossed areas will interlock with one another when, for example, the web is wound on to a collection roll. The surface deformation of the web edges provided by the embossing step protrude just enough to separate the successive wound layers. The embossed edge region can be later slit off prior to or subsequent to coating operations for forming a working photoreceptor belt. Benefits of edge embossed web material include: providing reduced slip between adjacent layers of wound material and between the web and the rollers in coating processes; and providing increased stability to the web edges and thereby improving the known "edge flop" effect. Similar approaches as described above have been employed in the paper and film coating industries to achieve the aforementioned and related advantages.
