Abstract: An apparatus for automatically applying trasfers to packages in any size of cartons, such as revenue stamps to cigarettes while in cartons. Initially, cigarette cartons of any size are loaded onto a conveyor belt where they are carried to the various stations of the apparatus. The apparatus is automatically adjustable to any size of carton by means of photoelectric cells. As the cartons are pushed through the apparatus, an improved plow head opens the cigarette cartons in preparation for stamping. Just before stamping, any improperly opened cartons are automatically ejected. An improved stamp indexer scans the stamps photoelectrically so a motor advances the correct number of stamps so that waste is reduced and defective stamping is avoided. Next, a gluing station applies glue to ensure that flaps stay down when the cartons are reclosed. Finally, the cartons are discharged onto a conveyor where a packing station aligns them and pushes them row by row into a case for shipment.
