Abstract

1367357 Stamping; making cans AMERICAN CAN CO 2 Aug 1971 [1 Dec 1970] 36309/71 Headings B3Q and B3A A thickened sidewall portion 76 is formed adjacent the open end of a metal can body during a drawing and ironing process by terminating the movement of the punch 12 to prevent the can body from passing completely through the last die. In the embodiment described, a pre-drawn cup is forced by the punch 12 through a first drawing and ironing die and second and third ironing dies, the stroke of the punch 12 being controlled in order to leave the thickened sidewall portion 76 which facilitates subsequent necking-in and flanging operations. After withdrawing the can body and punch 12 from the last die, the can body is removed from the punch 12 by an internal stripper within the punch 12 (not shown) and/or an external stripper 80.
