ABSTRACT:
A labeling machine has a rotor on which several oscillatingly driven pallet shafts are supported. Each shaft has a carriage shiftable transversely to the shaft axis. Glue pallets having partly cylindrical surfaces for being coated with glue are mounted to the carriage and are thereby movable from a radially outward position to a radially inward or neutral position for, respectively, contacting a glue roller and a label in a stack successively and for being retracted to neutral position out of the path of the roller and stack. The shafts have an enlarged central section which is rectangular in cross section and a complementarily shaped channel on a sleeve that carries the curved pallets is supported for sliding transversely to the pallet shaft axis. The sleeve is shifted by means of compressed air acting on a piston located in the enlarged portion of the shaft and is held tight in either active position or neutral position by applying compressed air constantly to one side of the piston while the other side is exhausting.
