Transfer device on a press

A device on a press, having a predetermined movement thereof, for incrementally conveying at least one workpiece in a longitudinal direction from a receiving station through at least one tooling station of the press used in connection with a means for conveying the at least one workpiece, the conveying means being moved back and forth in cycles in the longitudinal direction, as well as in a transverse direction substantially perpendicular thereto in order to grip or release the at least one workpiece, the device comprising:

• an external drive unit capable of rotational movement in synchrony with the movement of the press, wherein said rotational movement is driven by a motor;
• and
• a coupling attached to a portion of the conveying means and to a portion of said external drive unit;
• wherein the conveying means are moved in the longitudinal direction using said external drive unit, and said coupling is structured such that said external drive unit is mechanically connected to the conveying means in such a way that the conveying means can be moved back and forth in synchrony with the movement of the press without reversing the rotation of the external drive unit.
