Patent ID: 8763666

Claim:
Labelling machine for labelling containers, comprising: a container feed device; a labelling region; a container removal device; and at least one labelling unit for processing labels from a roll, the labelling unit including at least one label roll, a label feeder, a gripper cylinder, at least one gluing mechanism, a cutting device, the cutting device comprising a rotating vacuum roller and a rotating parting element which, on its circumference, has at least one parting tool, and a common support device holding the cutting device, the common support device having a base part and a cover part, the rotating vacuum roller and the rotating parting element being rotatably mounted to the base part in a desired spaced apart relationship relative to one another in a non-thermally-expanded condition, wherein the support device comprises a plurality of different materials, the support device having a mean coefficient of thermal expansion corresponding substantially to the mean coefficient of thermal expansion of the rotating vacuum roller and the rotating parting element such that, when in a thermally-expanded condition, expansion of the support device compensates for expansion of the rotating vacuum roller and the rotating parting element to maintain the rotating vacuum roller and the rotating parting element substantially in said desired spaced apart relationship.
