Abstract

Batch web film coatings from solution of, for example, belted photoreceptors, can produce edge effects which often yield increased layer thickness. Subsequent core winding of the web can induce severe web strain andor misalignments which can induce web damage. A sacrificial leader material remaining in a web coater between batches or nm could be edge shaped to control the edge support upon winding to compensate for web edge thickness perturbations thereby eliminating potential damage.
