Abstract
A doming assembly for doming the bottom wall of a can body. A bodymaker punch urges a can bottom wall first against a forming ring and then against a domer die. The forming ring forms an outer annular portion of a dome and the domer die forms a central portion of a dome in the can bottom wall. The sequential engagement of the can bottom wall by first the forming ring, then the domer die prevents flower dome formation and axial can body shortening.
