ABSTRACT:
An apparatus for opening folded boxes and delivering the opened boxes to a conveyor device of a cartoning machine including a supply magazine and a delivery device equipped with a suction gripper. In order that the flat-folded boxes will be reliably opened, the apparatus has a holding device with a suction gripper for exerting counter-action during the initial part of the opening operation. The flat-folded boxes are delivered to the holding device by means of a transfer device, suction grippers on the transfer device are moved back and forth on an arc-like path the end portions of which extend substantially perpendicular to the holding plane of the holding device and to the removal side of the magazine. In the initial portion of its return path, the suction gripper of the transfer device still holds the folding box firmly, so that the folding box already opens partially at that time.
