Abstract

A cup-shaped container is formed from a metal blank (13) by forcing the blank (13), carried by a mandrel (50) through a drawing die (21) to shape the blank (13) with a base (14) and an elongate cylindrical wall (15), and ironing dies (22,23) to thin and extend the cylindrical wall (15) along the mandrel (50). The mandrel (50) has circumferential a groove (57) into which metal is caused to flow during the ironing step and adjacent the groove (57) is a severing die (56) which co-operates with an ironing die (23) to trim the rim of the cylindrical wall (15) adacent the groove (57). The resultant container has an inner circumferential bead (60) at the rim, which strengthens the container and reduces the incidence of splitting.
