Abstract (en)
[origin: US2011174045A1] For the manufacture of can bodies as they are needed for the manufacture of aerosol cans or beverage cans, a special tool 2 is provided which combines the manufacture of the cup as well as the transformation of the cup into a can body into a single tool 3. The process is based on preferably round metal sheets which are first drawn in a first draw-stretching step of the tool 2 into cups and then are draw-stretched in a second draw-stretch process, the further draw- and slide-down-stretch to form can bodies. The drawing arrangements are the same in both operating steps. The tools required therefore are simple sturdy tools providing for a simple sturdy manufacturing process.
