Abstract

1511046 Etching process GILLETTE CO 23 June 1976 [5 July 1975] 28426/75 Heading B6J A dry cutting shaver foil having apertures separated by bars 2, of the kind disclosed in Specification 1,508,235 (Division B4), is made by cleaning a strip of metal, e.g. steel, coating it on each face with a photoresist 11, 12, exposing each face to radiation, e.g. ultraviolet, through suitable masks to produce after development the masking areas 11a, 12a, spray etching to form recesses 6 and to partly form apertures to depth 14, removing the masking areas 11a and further etching to remove more metal to complete the formation of the apertures and the bars 2. In the example, the back face is etched first and then completely masked with adhesive tape 13 before the front face is etched.
