Abstract

A cutting unit comprising a cutting drum, a drum knife, a counterpart knife, and a double-joint controller that controls swiveling about a first joint, which swivels the counterpart knife between a cutting position and a waiting position, and swiveling about a second joint, which permits adjustment of a knife gap that forms between the counterpart knife and the drum knife in the cutting position. The drum knife is disposed on a circumference of the drum such that rotation of the drum guides the drum knife past the counterpart knife to cut a label when the counterpart knife is in the cutting position. In the waiting position, the counterpart knife is out of active engagement with the drum knife. The second joint permits adjustment of the knife gap such that the knife gap remains adjusted independently of swiveling about the first joint.
