Abstract
The transfer conveyor system utilizes at least one endless conveyor belt of reinforced flexible rubber-like material with cogs or teeth on its underside and with a series of nests fitted into holes in the belt. Nests for carrying can end shells are attached at their opposite edges to the belt. The belt is supported by and routed around an idler drum, located outside the press frame posts and by a toothed drive drum located within the press frame adjacent the opposite frame posts. Progressive conversion tooling for making shells into completed easy-open can ends is located between the posts above and below upper and lower tooling sets. The drive drum is provided with circumferential teeth for a positive drive to the belt. Attachments of nests to the belt are located on transverse center lines which permit the flat nests to travel around the end turns of the belts. Shells are positively seated into the nests and held by a circular array of independent flexible stepped fingers as the nests are transferred through the conversion tooling. Completed ends are carried around the drum at the end of the upper flight, and the ends are ejected from the nest rings and moved [as by force from ai…
