1. A mask for copying documents, made from a single sheet of material folded in such a manner as to form a lower backing surface (15) and an upper, overlay, surface (20), the fold forming a spring hinge (11), characterized by the fact that the upper surface (20) is flat and the fold such that, as the material curves back upon itself, a linear gripper strip is formed between the upper and lower surfaces.
