Abstract:

This invention relates to punch presses having a transfer die and a work transfer mechanism for advancing individual workpieces progressively through successive tooling stations of such die at high speed comprising dual intermittent-feed transfer bars slidingly mounted for rotary movement and lifting of said workpieces off the tooling stations of said die, and associated clampbars which retain each workpiece on the transfer bars by free retention of the edges of the workpiece during transfer movement, and which transfer bars deposit said workpieces at the next successive tooling station by rotary movement to release the lifting support of each workpiece from below the same and from the free-retention clamping thereof from above in readiness for the next tooling operation.
