    Abstract: A transfer feed press for performing a series of press operations on a workpiece at a series of work stations where a plurality of finger units spaced along the work stations for gripping the workpieces move the same between successive work stations in the press. Servo motors, in association with the appropriate gearing, transfer the finger units along the X, Y, Z axes for positioning the workpieces at successive work stations. Separate servo motors are adapted to rotate a workpiece, gripped by the finger units, 180.degree., for performing press operations on both sides of the workpiece.
