Abstract
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.
