ABSTRACT:
Strip feeding apparatus comprises a feed screw having a feeding thread on its surface. The thread is received in notches in one edge of the strip so that rotation of the screw advances the strip. Guides are provided for guiding the strip along the feed path and maintaining the strip in engagement with the thread. The thread may have a portion of each turn which causes no feeding during each revolution so that strip is fed intermittently. The feeding apparatus may be used under a wide variety of circumstances and is disclosed in conjunction with a stamping and forming or similar machine.
