Abstract

365,463. Punching; stamping. ARMSTRONG, J. J. V., 12, Church Street, Liverpool.-(Continental Can Co., Inc. ; 100, East 42nd Street, New York, U.S.A.) May 22, 1931, No. 15131. [Classes 83 (ii) and 83 (iv).] Making hollow-ware.-Apparatus for producing scroll-edge blanks from which tin can tops and bottoms &c. are to be blanked out, comprises means for notching the edge of the sheet, trimming out the edge portion between said notches and stamping out alternate blanks spaced exactly the double width of a blank whereby the alternate blanks fall out. The sheet 10 is fed to the dies step by step by fingers 19 reciprocated in timed relation to the reciprocating ram 14 by means of the crank 27, and is positioned by gauge fingers 19a and stops 20. Punches 13 on the ram co-operate with dies 15 to form triangular notches a in the edges of the forward part of the sheet. The sheet is then fed so that the part located between these notches lies over the opening in the lower die 12. The scroll-edge die 11 then descends to shear out a blank A, the punches 13 simultaneously operating. The sheet is again fed forward a distance equal to two blank widths, bringing the scrolled forward edge of the sheet beyond the opening in the lower die 12, and that located between the notches a directly over said opening. On the downstroke of the ram, two scroll-edge blanks A, B are sheared out, A being punched through the opening in the lower die and B falling incident. Simultaneously the blades 17, 18 trim off the portions b<3> at the ends of the blanks B, such recoveries being usable for punching out small articles therefrom, the waste strips a<4> fall away and the next set of notches a is formed.
