ABSTRACT:
A device for processing a batch or stack of die cut sheets to sever the individual blanks into piles of blanks characterized by a lower frame supporting a fixed plate and a slidable plate, an upper frame movable relative to the lower frame supporting a fixed plate and a slidable plate, each of said fixed and slidable plates supporting a pair of transversely movable tables so that when a batch of die cut sheets is disposed between the movable tables and the upper frame is lowered, the movable tables can cause a separation of the blanks along two orthogonal directions. The device also includes a conveyor which is mounted in the frame for conveying the batch into the device and the piles out of the device with the conveyor being retracted as the upper frame is moved into clamping engagement with the batch of sheets.
