ABSTRACT:
In a rotary turret-type machine, in which operations are performed on successive can body cylinders (8) or the like by a mandrel (159) inside the workpiece co-operating with a beading rail (176), each workpiece is guided smoothly into a cradle (151) which so supports and locates it throughout its stay in the machine that axial movement of the mandrel is unnecessary. Each cradle is reciprocated towards and away from the mandrel by a fixed cam (145). Each cradle has a spring loaded support roller permitting eccentric support of the can body during beading. Each mandrel preferably has a quick-acting coupling (200) permitting temporary radial displacement of the mandrel without loss of parallelism to accommodate a can body side seam. This coupling consists of a spring mounted support plate (305) engaging a register plate (304) through three balls (306) mounted in seats (307) in the rings to give radially-yielding tripod support.
