Abstract

1420830 Making dry shaver cutters RONSON PRODUCTS Ltd 1 April 1974 [2 April 1973] 15759/73 Headings B3E and B3A [Also in Division B4] A method of making an inner cutter for a dry shaver of the kind comprising a perforated foil against which is reciprocated an inner cutter having a plurality of blades mounted in a rigid support, consists in corrugating a ribbon transversely to its length and winding the corrugated ribbon on edge to form a helix. The ribbon may be wound so tightly on a mandrel that the latter serves as the final support, or the inner edge of the helix may be adhered to the mandrel. Alternatively, the ribbon 4 is removed from the mandrel, and partly embedded in a body or metal or plastics 5 constituting the final support. At least half of each turn may be embedded, or all but the outer edge of the turns may be embedded. Finally the exposed outer edge of the helix is ground to a cutting edge.
