ABSTRACT:
There is disclosed a manufacture of a continuous hinge. The process is as follows. A metal strip is fed intermittently by a predetermined length towards a press-machining station where the strip is simultaneously cut and bent to form a hole, flap, swaged flap and loop during the stoppage of the strip. The strip having loops is cut into predetermined length to form leaves for a hinge. A pair of leaves are assembled by inserting a pintle through the aligned loops, and the assembly is reformed by roll means.
