ABSTRACT:
Apparatus for forming hinges from strip stock and for applying the hinges to cards and pockets. Hinge blanks including a pair of hinge legs are stamped from the strip stock and the barrel of the hinge partly formed at a first station. The blank then moves laterally to a second station where the legs are bent at a right angle to the hinge body and the barrel further shaped. Thereafter, the hinge continues in the same lateral path to a third station. Here, the formation of the barrel is completed; the hinge legs are driven through a pocket or card theretofore brought to the station; and the hinge legs are then bent over and against the pocket or card to secure the hinge to it.
