  • the containers Before labeling the containers in the beverage industry with a medium such as. B. filled with water, lemonades, juice, beer or the like. It may be necessary for the media to be filled to be filled into the container preferably at approx. 2 to 4 ° C. The consequence of this is that the containers can become damp immediately after filling due to condensed air humidity on their outer surface of the container. Depending on the current conditions of air temperature and absolute or relative humidity in the spatial environment of the filling, the containers even get really wet on their outer surface. The problem with this is that no labels adhere to the moist or wet outer surface of the container or that the labels slip on the outer surface of the container. As a result, optimal labeling is not possible.
  • labeling machines In order to remove the condensate on the outer surface of the container, labeling machines are known in which a drying tunnel is arranged before the actual labeling with at least one labeling unit.

In continuous operation, the containers are dried sufficiently by this procedure so that subsequent labeling on the outer surface of the containers is possible.

Rapid rejection from the transport route to the drying tunnel and subsequent re-supply to the drying tunnel of the containers enables the containers or the medium filled into the containers not to heat up due to excessive transport along the transport route of the labeling machine.
