An apparatus is disclosed for the feeding of oval-shaped open end wire links seriatim, from an open-link feeding bar magazine, to a groove in a movable link-forming slide tool. Subsequent upward movement of the link-forming slide tool carries the open oval-shaped wire link into internal surface contact with a fixed position link center-forming anvil. Closed chain links or findings are mounted over the ends of the open wire links at this point, and further upward movement of the link-forming slide tool results in the closure of the previously open wire link to a desired configuration such as oval or round, and its assembly with the preformed ornamental objects is completed. The present device may be employed in various power driven modes.
