Abstract

1285549 Making cutter foils; stamping PHILIPS GLOEILAMPENFABRIEKEN NV 24 Sept 1970 [25 Sept 1969] 45622/70 Headings B3A and B3Q [Also in Division B4] A cutter foil for a dry shaver is made by pressing a metal foil 2 between a rubber cushion 3 and a die 1 having raised parts 5, each comprising superimposed portions 6, 7 separated by a step 8. When the rubber cushion 3 is moved downwards, holes are punched out of the foil 2 by the portions 6 of the die 1, after which the apertured foil 10 is pushed from the steps 8 down on to the base surface 9 of the die 1 causing the edges of the holes to be turned over. The foil is finally ground. In alternative embodiments (Figs. 5 and 6, not shown) one or both portions 6, 7 of the die 1 are frusto-conical and the step 8 is frusto-conical or formed by two torroidal surface portions. The holes may alternatively be diamond or pentagon shaped. [GB1285549A]
