Abstract
Method and apparatus for forming a non-cylindrical can body having a bottom wall and a side wall from an elongated flat strip of sheet metal having a known grain orientation. A non-circular blank is formed from the metal strip in a first forming press with the grain extending in a known direction. The blank is drawn by the press into a non-cylindrical can blank with the grain direction being known in the bottom wall of the can blank. The can blank is moved toward a second press and is oriented automatically as it passes through an orienting station so the direction of the grain is known when entering the second press. The can blank is redrawn to form a non-cylindrical can body with a known grain direction in the bottom wall of the can body by maintaining the orientation of the can blank as it is drawn and redrawn in the second press.
