Abstract
A photoreceptor belt system in which the belt is drawn by vacuum against a flat surface as the belt moves around a closed path has an improved platen cloth or mesh extending over the surface for preventing the belt from contacting the surface, the open area of the mesh being between 20% and 80% of the total area of the mesh. Nylon netting having an open area equal to approximately 40% of its total area has been found to be particularly satisfactory.
Claims2
An improved photoreceptor belt system having an endless flexible photoreceptor belt, means for mounting the belt for movement around a closed path which includes a flat run, means defining a planar surface along the run, and means for drawing the belt toward the surface as the belt moves around the closed path, wherein the improvement comprises:
- a mesh extending across the surface for preventing the belt from contacting the surface as the belt moves around the closed path, the open area of the mesh being approximately 40% of the total area of the mesh to minimize the rate of contamination of the mesh and consequently minimize the coefficient of friction between the photoreceptor belt and the mesh.
