Method for manufacturing pre-assembled, two-part merchandise display hooks and the like

An improved method of forming and assembling two-part merchandise display hooks, including new design features of the hook itself, enable two-part hooks to be manufactured and assembled at extremely low cost. Wire from a continuous length is gripped and bent to form the outer portion of the hook. The wire is then severed and bent in a single operation to form a hook-mounting portion. While the severed wire remains gripped by its shaped outer end, a preoriented and guided base member is applied over the just-formed mounting portion of the wire. A retractable bend-forming member is withdrawn when the base member is applied to the wire, to enable the bent portion to be fully received within the plastic base. Major manufacturing economies are realized.
