ABSTRACT:
The provision in a conventional punch press of a cyclicly-operable transfer mechanism which is adapted to be bolted to the stationary die shoe of the press in between successive forming stations and has associated with it a pair of blank-gripping jaws which travel generally in web line fashion between first and second stations for blank-transferring purposes while at the same time rotating so that each blank is reversed from end to end upon completion of the transfer operation. During the transfer, the jaws swing or revolve in a circular path about a vertical axis so that directional reversal of the jaws accounts for a major portion of the blank displacement. Additional web line jaw displacement takes place at the first forming station in order to bring the jaws while in an open position into straddling relationship with the leading edge of a blank prior to gripping thereof and similar web line jaw displacement takes place at the second forming station in order to withdraw the open jaws from the transferred blank after release thereof. Components of vertical jaw movement during the transfer take place, if required, for the purpose of lifting the blank from the plane of the web and compensating for differences in elevation of the blank at the two forming stations.
