ABSTRACT:
In a method of forming at an open end of a can body an out-turned end flange and an adjoining inward bead, the free end of the can body is carried frictionally in an annular groove formed in a transverse end face of a rotating driving head. In a first stage, an inner support roll is placed inside the can body in contact with its inner surface at a position spaced axially from the driving head, and an outer work roll is progressively advanced against the outer surface of the can body adjacent the driving head so as to form the inward bead, and thereby gradually retract the open end of the can body within the groove. In a second stage, the inner roll is advanced to a can body stabilizing position, and the work roll is then advanced further so as to withdraw the open end of the can body from the groove and then to turn it radially outwards as the can body end advances eccentrically across the rotating end face of the driving head. During the formation of the end flange the inner roll is progressively advanced so as to maintain its can stabilizing action while the can body end progresses across the rotating end face of the driving head.
