An integrated system and apparatus for completely forming the body of a two-piece can in one press, including performing the operations of cupping, drawing, redrawing, bottom profiling, and trimming. The system includes the concept of performing all of the operations required to form the body of a two-piece can in one press and includes feeding the precoated stock material, either in the form of sheet or coil, through a lubricator and into a feeding apparatus which, in turn, selectively feeds sufficient quantities of the stock material into a press. The press carries the double die necessary to perform the typical blanking and cupping operation and passes the cups out of the press in two lanes onto cup conveyors which feed them back into the press whereupon the draw-redraw dies on both sides of the cup die perform the additional steps of first redraw, second redraw, bottom profile, and trimming. The formed containers are then conveyed to secondary processing stations such as beaders, testers, or palletizers. In this fashion, a complete can body can be formed cheaply and economically without the normal expense of conventional forming mechanism.

A method of forming container bodies from flat stock material in a reciprocating press, comprising the steps of: (A) passing the stock into the press and blanking and cupping at least two cups in a central work area on each press cycle; (B) forcing the cups through the die and transferring the cups

A method of forming container bodies from flat stock material in a reciprocating press, comprising the steps of: (A) passing the stock into the press and blanking and cupping at least two cups in a central work area on each press cycle; (B) forcing the cups through the die and transferring the cups out of the press along two divergent paths; (C) directing the cups from said divergent paths to two parallel paths and returning the cups to the press to work areas on each side of the central work area; (D) finish forming the cups into container bodies within the press; and (E) again transferring the containers out of the press.
