LABELING DEVICE WITH ELECTRONIC DISTANCE MONITORING

摘要

The invention relates to a labeling device and to a method for operating such a labeling device on a deep-drawing packaging machine. The labeling device includes two cross-web labelers, each displaced on one common guide system, and each having a drive and power supply. The labeling device further includes a safety controller configured to calculate a distance between the two cross-web labelers and interrupt the power supply of each drive of the cross-web labelers when the calculated distance is below an invariably predefined safety distance so as to ensure a reliable deactivation during the displacement of the cross-web labelers in the event of a fault.
