Abstract:
A method and apparatus for forming a container component has a fixed stock plate and cut edge mounted on a base at a first level for forming a disk-shaped blank from a strip of sheet material. A blank and draw die is mounted at a second level which forms the disk-shaped blank into a shallow cup upon advancement of a punch assembly through the die. A profile pad is mounted at a third level on the base and imparts a profile on the bottom wall of the shallow cup as the punch assembly continues a downward stroke. An air stream ejects the profiled container component from the press at the third level.
