ABSTRACT:
This invention provides method and apparatus for reshaping the bottom wall of an aluminum can body wherein a mold member having a generally cylindrical outer surface having a longitudinal axis and a contoured bottom surface is mounted for rotation in a support structure and an aluminum can body having a generally cylindrical sidewall having a longitudinal axis and an integral bottom wall is secured on the mold member so that an annular portion of the bottom wall contacts at least an annular portion of the contoured bottom surface and the longitudinal axes thereof coincide. As the mold member and the can body are rotated, resilient forces are applied to the bottom wall using a tool member having a spherical surface which is moved in a diametrical linear direction across the bottom wall to reshape the bottom wall into conformation with the contoured bottom surface.
