The timed-feed stage of a packaging machine for the timed feed of piece goods (3) supplied irregularly in a plurality one next to and one behind the other comprises a plurality of conveyor bands (5) arranged parallel and next to one another and separated from one another by lateral limitations forming channels (4), and build-up stop means movable into the paths of movement into the piece goods (3). At the same time, a shower plate (30), flow-connected to a compressed-air source (35), for generating an air cushion partially under the built-up piece goods is arranged under the conveyor bands (5) in a predetermined region of at least two successive piece goods in front of the build-up stop means (16, 17). As a result of these measures, it is now possible, in front of the stopping point, to reduce the frictional connection between the running-on products and the conveyor bands as a result of the generation of the air cushion to such an extent that, when the built-up products butt against one another, it becomes impossible for them to be pushed over. <IMAGE>
