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°, for performing press operations on both sides of the workpiece.

In a transfer feed press for performing a series of press operations on a workpiece at a series of work stations, a transfer feed system comprising the combination of a plurality of finger units spaced along said work stations for gripping said workpieces and moving the same between successive work stations in the press, means mounting said finger units for independently controllable movement along a plurality of axes including a vertical axis defining the direction of vertical movement of said finger units for raising and lowering the workpieces at the various work stations of the press, a substantial portion of said transfer feed system being raised and lowered along with said finger units, a separate electric servomotor for controlling movement of said finger units along each of said axes, each of said servomotors being independently controllable by electrical control signals, and fluid operable counterbalancing means for applying an upward force to said transfer feed system, said counterbalancing means operating independently of said means for moving said finger units along said vertical axis, said upward force being substantially equal to the weight of said feed system so that said servomotor for controlling movement of said finger units slong said vertical axis is not required to overcome the weight of said feed system.
