Abstract

118,512. Gare, T. Nov. 3, 1917. Punching; punches.-Sheet metal is stabbed or perforated and burrs or projections formed on one side by passing the sheet between a serrated or spiked roller and a grooved roller or a flat rotary table. The teeth or spikes may be arranged heli. cally or in rings and may be set like saw-teeth The toothed roller may be made in one piece or may be in sections separated by disks m, Fig. 5 of the desired thickness. The other roller b may be grooved as shown, so that corrugations n, Figs 9 and 10, are formed in the plate between the rows of teeth p. Fig. 16 shows an apparatus in which a grooved circular table t is used to support the sheet. The table is moved under the roller a b; means of a screw rotated by a handle.
