Abstract: The invention relates to a vacuum cylinder unit for transferring labels to containers in a vacuum-supported manner, and a labeling device equipped with said unit. The vacuum cylinder unit comprises a drive shaft and a vacuum cylinder which is coupled thereto in a centered and driving manner by means of a zero-point clamping system. Because the zero-point clamping system comprises a clamping pin which is integrated into the vacuum cylinder and a clamping chuck which is rigidly connected to the drive shaft for securing the clamping pin, the vacuum cylinder can be manually lifted off the drive shaft by a small vertical stroke and the majority of the weight of the zero-point clamping system can be moved into the region of the drive shaft. This also reduces the amount of equipment needed for the vacuum cylinder which is designed as a format-specific interchangeable part.

Abstract: A vacuum cylinder for a labeling apparatus may include a bottom support and a plurality of spaced-apart supporting elements. The bottom support may have a receiving opening for receiving a shaft in a rotationally fixed manner. The supporting elements may have a longitudinal dimension extending substantially perpendicular to a plane of the bottom support. Each of the supporting elements may be releasably connected to the bottom support via a first end section, and the bottom support may have a plurality of cutouts arranged in a radial direction of the bottom support between the receiving opening and the supporting elements.
