Abstract
332,076. Humphris, F. July 31, 1929. Perforating ; cutting nails; punches. - Sheet stock for use in the manufacture of sheet metal nails of corrugated or like cross section is provided prior to the action of the combined blanking and corrugating punches with triangular openings or with V- or W-shaped slits at the parts of the sheet that subsequently form the points, so that the points of the blanking punches are relieved from all cutting duty. Thus perforations a, Fig. 1, may be produced at properly pitched distances by the punches, Fig. 6, or slits a<1>, Fig. 2, by the punches, Fig. '7.
