Abstract
A web with overlays for use in the document presentation device of a photographic copying machine has several sheet-like sections with overlapping portions which are separably coupled to each other by snap fasteners and carry overlays which are welded thereto by the application of heat and pressure. The overlays are applied to those sides of the sections which are coated with layers of photographic emulsion.
