Abstract: This invention relates to a workpiece translation mechanism for moving successive workpieces through successive stations of a transfer stamping die. Workpiece engaging mechanisms are provided on a top subframe which is mounted on an intermediate subframe for horizontal motion parallel to the path of the workpieces through the transfer die. The intermediate subframe is mounted on a bottom subframe for horizontal reciprocating movement transverse to the path of the workpieces. The bottom subframe is mounted for relative vertical reciprocating motions with respect to the bed of the transfer press. Appropriate mechanical driving arrangements are provided for both the top and intermediate subframes so that both horizontal movements are respectively accomplished with an harmonic acceleration and deceleration of the respective subframes so that they are at essentially zero velocity when they reach each extreme of their reciprocatory positions.
