This invention relates to an apparatus and a method for unstacking preformed products (2), for example packaging units, stacked in a stack, these products comprising for example planar parts (4) and projecting parts (3) which are all stacked onto and into each other in line, wherein the method comprises, - placing a gripper with at least a single suction cup unit (51)of flexible material, more particularly a suction mouth thereof, on a planar product part (4) of such a product, - suction-engaging such a product, - conveying the product to a delivery location, and - releasing the product, wherein upon suction the planar product part (4) is pulled against a plate (55) which is part of the apparatus. It has been found that in this way in a suitable manner stacks of flexible and thin-walled packaging units can be unstacked, without the stack being disturbed or the packaging unit taken off being damaged or being picked up in the wrong position. |
