  • Parts depository, particularly for large-area workpieces in a transfer press handling large workpieces
    Patent number: 4503766
    Abstract: The present invention relates to a parts depository particularly for large-area workpieces processed in a transfer press handling large workpieces, with the tool free stage disposed between the machine columns being designed as a so-called empty stage for the deposit of the workpiece parts.To avoid the manual work previously required to adapt the parts depository to the new workpiece when changing from one workpiece type to another and to make the change as fast and automatic as possible, the present invention proposes to arrange a plurality of supporting elements in the empty stage so as to serve as support for the workpiece part, with the supporting elements being adjustable and settable in height.
