ABSTRACT:
A method and apparatus for reforming the bottom of a drawn and ironed or a drawn beverage container, and a container made by that method. The container for which this method and apparatus are suitable has a vertical axis; a generally cylindrical side wall parallel with the vertical axis; an outer annular wall; a convex U-shaped portion; a preformed bottom wall including a center domed portion; and an annular, substantially vertical wall joining the domed portion and the convex U-shaped portion. The method comprises supporting the container in a jig, the jig having a bottom peripheral profile portion substantially corresponding in shape to the outer annular wall of the container. The bottom peripheral profile portion of the jig is then mated with the outer annular wall. A reforming roller is brought into engagement with the substantially vertical wall. The reforming roller rotates along the vertical wall and about an arcuate path, affecting the angle of the substantially vertical wall.
