  • each container carrier 6 is assigned an independent electric motor drive 6.1.
  • Other drives which allow a change in the container peripheral speed of the rotating container 2, can be used.
  • the labels are exclusively so-called wrap-around labels. It goes without saying, however, that the method presented here and the labeling machine presented here are likewise suitable for processing all other known types of labels, so that the scope of protection of the present invention naturally also extends to such applications.
  • label narrow side in case of doubt should also be understood to mean the side of the label with which the label is transported in advance in the transport direction in the transport of the label.
