This system is a combination of a robot & high level palletiser. It lifts the bags vertically & a robot style gripper places the bags into a layer that allows overlap to form a layer. The layer is pressed on all four sides and the pallet is then raised and the layer is placed on the pallet. The layer top is pressed to form a flat surface for the next layer.
This system is ideal for stitched bags and provides a very high quality finished stack.
