Zusammenfassung:The present invention provides a transfer device for use in a machine tool of the type in which a workpiece item is moved in sequence between a plurality of operation stations, and in particular for transferring large blank materials through a multi-stage process by engaging and employing both a cross-bar-type (17) and a finger-type (22) transfer device. The cross-bar type transfer device includes a blank attachment member (18), adaptable to specific blank shapes, that enables transfer of large blank materials without sufficient rigidity for quicker or simpler transport methods. The finger-type transfer includes multiple fingers suitable for rapid transport of blank materials that, after initial processing, have sufficient rigidity for rapid transport.
