Abstract
Abstract A device for packing filled bags of low weight into boxes comprises a suction box (1) movable along a horizontal track between a pick-up position and a delivery position. The suction box is provided with a number of suction cups (2). To avoid the problem of bags falling from the suction cups or not taken up by these cups the device comprises means (17, 18, 19) for pushing the bags upwards against the suction cups.
