Abstract
A conversion press assembly for forming easy open beverage cans and a transfer belt conveyor therefor. The press assembly comprises a main press having tooling therein for forming the can ends and a can end transfer belt extends therethrough to carry can end blanks from a downstacker or other supply apparatus. Attached to the main press frame is an auxiliary, tab press having its own crankshaft but being driven off the same drive assembly as the main press. Strip stock is fed into the tab press wherein the tabs are formed, and the tabs, still in strip form, are then fed transversely into the main press for attachment to the can ends at a staking station. The transfer belt comprises a plurality of carriers mounted on a flexible belt wherein the carriers include flexible fingers for resiliently gripping the can ends.
