Abstract:
Apparatus and method for forming cup-shaped container bodies in a press by blanking a disk shaped metal blank from a flat metal sheet by a cutting die and forcing the disk blank through a blank and draw die by movement of a draw horn to form a generally cylindrical-shaped can body. Next, the cylindrical shaped body is moved by pressurized air through the bore of a cylindrical-shaped cup drop sleeve. The cup drop sleeve has an inner diameter just slightly larger than the outer diameter of the just formed cylindrical metal body thereby reducing the amount of spring back in the metal and setting the metal in the formed body to reduce distortion and maintain roundness thereof as the body is being ejected through the open bottom of the drop sleeve.
