Abstract

A labeling apparatus includes a rotating vacuum drum and a pair of vacuum holders on the drum that are switched by rotating switches between a working position for gluing labels and a rest position in which the vacuum holders avoid an application of glue. Actuators cause the switches to transition between operating positions. Stationary switch controllers initiate transitions between the operating positions of the switch, thereby causing the holders to transition between their two positions.
