ABSTRACT:
A method and apparatus for aligning opposed telescopically engageable cut ring and blank and draw die when mounted in a can body forming press to form non-round disc-shaped blanks which are subsequently formed into container bodies. A pair of opposed precision formed notches are formed in the peripheries of the spaced press components and a precision formed key is inserted into the notches. The key is then slidably removed from the notches. The notches are precisely located with respect to each other and to major and minor axes of the press components so that said major and minor axes align with each other when the key is seated in the notches.
