A method and apparatus for reforming a bottom of a drawn and ironed beverage container is disclosed. The container has a longitudinal axis and a side wall parallel with the longitudinal axis. The bottom has an outer annular wall, a convex U-shaped portion and a preformed bottom wall. The preformed bottom wall includes a center domed portion. The bottom further has an annular, substantially longitudinal wall joining the domed portion and the convex U-shaped portion. The apparatus comprises a roller movable from an inward position where the roller does not contact the annular, substantially longitudinal wall to an outward position where the roller contacts the annular, substantially longitudinal wall, and a movable actuator to move the roller into engagement with and circumferentially about the annular, substantially longitudinal wall to reform the substantially longitudinal wall. The movable actuator moves the roller into engagement with the annular, substantially longitudinal wall to reform the substantially longitudinal wall to achieve a negative angle (A) relative to the longitudinal axis of the container.
