ABSTRACT:
An apparatus for stacking cards, printed sheets or similar products has feeder stations situated in a row and a conveyor with pushers. The feeder stations include spaced inner and outer tables. Individual products are deposited on the tables at the feeder stations. The inner tables are provided with lateral stops and a plurality of nozzles which emerge from the upper surface at a shallow angle towards the stop. Compressed air emitted from these nozzles creates a suction force which stabilizes the products on the tables. The pushers extend between the tables and push the product through a cut-out in the outer table onto a stack of products moving in synchronization on the conveyor below the tables.
