Areal metal element with slits and folded out to expand and form apertures over central region

摘要

A reforming assembly for simultaneously reforming and reprofiling a bottom portion of a metallic container is provided. The reforming assembly generally includes a roller block having a pair of reform rollers and two pairs of outside reprofile rollers. A biasing means is operably interconnected to the reform rollers, such that the reform rollers extend to contact the inner surface of the bottom portion of the container when contacted by the bottom portion of the container. The outside reprofile rollers engage with an outer surface of the bottom portion of the container. The container reforming assembly is rotated, while maintaining the container body in a static non-rotating position, to create an internal can profile on the inner surface by the pair of reform rollers, and an external can profile on the outer surface by the outside reprofile rollers.
