Abstract

A vacuum drum for container labeling includes vacuum holders for holding a label. Each holder has a bistable rotational switch that switches between operating positions as a result of its switch actuator interacting with stationary switches during the drum's rotation. In one operating position, a label receives glue from a glue station. In the other, the holders avoid engagement with the glue station.
