ABSTRACT:
A re-stacking device for stacking partial stacks of sheet material into a complete stack is disclosed. The device includes a slide mounted for raising and lowering on a machine support and carrying a table top which is horizontally movable back and forth between two end positions. A partial stack is placed on the table top in one of its end positions and moved with it to the other end position above a started stack supported on a stationary carrier. In this other end position the slide is lowered until the table top is a short distance above the top of the started stack. Hydraulically operated clamps are then moved toward the forward edge of the partial stack, and closed to grip this forward edge, whereupon the table top is horizontally withdrawn from under the partial stack so that the latter is deposited on the said started stack. Thereafter, the clamps are opened and withdrawn from the stack. The clamps are preferably mounted for horizontal movement on a second slide which can be raised and lowered on the machine support relative to the first mentioned slide.
