ABSTRACT:
The invention concerns a device for conveying layers comprising a multitude of individual objects, in particular glasses, cans, etc., preferably for loading and unloading pallets, a suction head being provided for picking up a layer of individual objects, which suction head has a plurality of suction holes. On the one hand, said suction holes face the top side of the objects and, on the other hand, are connected to a source of negative pressure. To avoid a breakdown of the negative pressure as a result of suction holes not being allocated over individual objects, a long flow duct is connected to each suction hole on the side facing away from the individual objects, which flow duct is coupled with the source of negative pressure or the suction chamber.
