In order to make it possible to change over quickly and easily to different label sizes and shapes in a labeling apparatus for the application of labels to packages and goods comprising a label dispensing device and an air-blast labeling device, wherein the label dispensing device supplies labels individually from a supply to the air-blast labeling device and wherein the air-blast labeling device has an underpressure chamber with a suction plate having a plurality of openings for drawing in the labels supplied by the label dispensing device, a source of compressed air with a compressed-air distributor which has an air-blast plate arranged adjacent the suction plate and provided with a plurality of openings, as well as a compressed-air pulse generator which directs a blast of compressed air from the source of compressed air through the air-blast plate of the compressed-air distributor and through the suction plate against the label held by the suction plate in order to release this from the suction plate and convey it to the package or article, it is suggested that the air-blast labeling device comprise between the suction plate and the air-blast plate a slide element which is mounted for displacement in such a manner that in various adjustment positions it covers or releases variable surface areas of the suction and air-blast plates for the passage of air drawn in or expelled.
