Abstract: A crimping tool, for crimping eyelets or deforming hollow, male rivet fasteners, having a plier-like configuration. Opposed jaws with handles and linkage for movement of the jaws towards and away from each other is provided whereby a metal fastener is deformed into a fastening position. One of the jaws, in one embodiment, carries a platen surface against which one end of the fastener abuts while the opposed jaw carries a pin forming member which is received in the hollow tubular portion of the fastener and which is subsequently deformed or cold formed to form a locking, retaining collar or flange. In another embodiment, the crimping tool is provided with a dual pin forming jaw and a dual eyelet or fastener may be acted upon in a single operation of the crimping tool.

Abstract: A method of producing an imprinting device having a supporting member and an impression conforming film thereon comprising depositing a thin, conformable elastomeric coating on a web from a mixture of resinous elastomer, filler and liquid solvent, drying the coating to form a film; applying a coating of wet ink on one surface of the film and bonding the film to the supporting member and the method of producing the thin flat conformable film.
