A processing unit for rotational processing includes at least two processing cylinders and a machine frame. A first processing cylinder is movably mounted in the machine frame, a second processing cylinder is stationarily mounted in the machine frame and a pair of support members is provided for each respective processing cylinder. A respective support member of the second processing cylinder has a solid joint, a manipulator and an annular segment attached to the solid joint and contacting one support member of the first processing cylinder. A solid joint is linearly displaceable by the manipulator and an annular segment is linearly displaceable therewith. A gap dimension between the processing cylinders can therefore be adjusted in a simple, accurate manner with precise repeatability. A label printing machine having the processing unit is also provided.

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 printing cylinder assembly for a printing machine includes a rotating shaft pivotally supported at one axial end shaft section thereof in a cantilever structure, and a sleeve cylinder removably mounted on the rotating shaft so that the cylinder can be fitted on and extracted from the rotating shaft from the other axial end side of the rotating shaft. The rotating shaft is formed at one axial end side thereof with a sleeve cylinder supporting tapered surface, and the sleeve cylinder is formed at one axial end side of an inner diameter portion thereof with a tapered surface, whereby the tapered surface of the sleeve cylinder can be fitted on and in close contact with the sleeve cylinder supporting tapered surface of the rotating shaft and thereby detachably coupling one axial end portion of the sleeve cylinder with one axial end portion of the rotating shaft.
