  • Patent number: 4190408
    Abstract: Apparatus for automatically loading and unloading a press having vertically movable die halves comprises a frame positioned adjacent the press, a movable carriage mounted in the frame for longitudinal movement toward and away from the press, and a blank holding table mounted in the movable carriage for rotation about a horizontal axis, with a gripping mechanism for holding blanks being mounted on one side of the table and a nesting device for holding finished products being mounted on the other side of the table. The gripping mechanism holds blanks in a position that duplicates the charge placement pattern in the mold. The apparatus is operated by a control mechanism such that after blanks are placed in the gripping mechanism, the gripping mechanism is actuated to hold them to the table and the table is turned upside down. The table is then extended to a position between the separated halves of the die, and the gripping mechanism is released, causing the blanks to be transferred to the lower mold cavity.
