In order to receive and stack newly moulded concrete blocks, a suction foot is assigned to each one of the latter, which suction foot is connected in an air-conducting manner via a suction pipe assigned to it in each case to a vacuum generator which can be switched on and off. In order to obtain an effective suction force and therefore holding force for the individual concrete blocks, without deforming their as yet unset surface in the process, the suction foot is provided on all sides in the edge region of its underside with a replaceable rubber sealing lip. In addition, knobs which project above the surface of the suction region and which are to prevent the pulling of the green concrete blocks up to the suction holes are distributed in the enclosed part. <IMAGE>
