A processing unit, for example a printing unit, for the rotational processing of a web-shaped or sheet-shaped substrate, includes a machine frame, at least a first processing cylinder movably mounted in the machine frame, a second processing cylinder stationarily mounted in the machine frame, and a pair of support members associated with each respective processing cylinder. Each support member of the second processing cylinder has an annular segment, a linear guide, a guide body fixed to the machine frame and a manipulator. Each annular segment contacts a respective support member of the first processing cylinder, and each annular segment is linearly displaceable along the linear guide by a respective manipulator. The processing unit permits a gap dimension between the processing cylinders of the processing unit to be adjustable in a simple, exact manner with precise repeatability. A label printing machine having the processing unit is also provided.

Processing unit and label printing machine having the processing unit

A device for punching labels from a substrate web having a carrier layer and a label layer includes a punching installation for punching labels. The punching installation has a delaminating installation for separating the label layer from the carrier layer, a metallic non-suction revolving counterpunching belt for conveying the label layer during a punching operation, and a relaminating installation for reconnecting the label layer, provided with punchings, to the carrier layer. A method for punching self-adhesive labels is also provided. In this way, a thin carrier layer can be used, and it is ensured that the carrier layer is not damaged during punching.
