Abstract: 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.

Abstract: A diecutting device, in particular for cutting labels, includes a diecutting cylinder that rotates about an axis of rotation, a counterpressure cylinder that rotates about an axis of rotation essentially parallel to the axis of rotation of the diecutting cylinder and has a cylinder body, and bearer rings assigned to the cylinders and rolling off on each other. A spacing between the diecutting cylinder and the counterpressure cylinder is adjustable. A respective bearer ring assigned to the counterpressure cylinder is connected to a counterpressure cylinder shaft and each end of the cylinder body of the counterpressure cylinder is connected to the counterpressure cylinder shaft by a respective connecting link guide.

Abstract: A device for heating at least one tool that is disposed on the circumference of a rotating cylinder, for example on the circumference of an embossing cylinder. The embossing tool is produced from a magnetizable material and it is fixed to a carrier sleeve that is produced from a non-magnetizable material.

Abstract: A die-cutting device for die-cutting labels includes a die-cutting cylinder and a counterpressure cylinder. A distance between the die-cutting cylinder and the counterpressure cylinder is adjustable. Accordingly, the die-cutting cylinder is locked in position by a locking force and the counterpressure cylinder is displaceably supported by a guide. The locking force and the guide generally form a right angle. A narrow-web printing press includes such a die-cutting device.

Abstract: A compact printing unit includes a plate cylinder, an impression cylinder, and an ink applicator roller in a printing press, in particular a label printing press. In the printing unit, the plate cylinder is disengageable from cylinders contacting the plate cylinder for the purpose of format variation. The plate cylinder is pivotable about the impression cylinder about a pivot axis which is parallel to the axis of rotation of the impression cylinder and a distance between the axes of rotation of the plate cylinder and the impression cylinder is variable. A printing press and a method of producing labels or self-adhesive labels in a printing press are also provided.

Abstract: A printing unit of compact construction includes an impression cylinder and a printing form cylinder to be pivoted around the impression cylinder about a pivot axis running parallel to an axis of rotation of the impression cylinder. A spacing between the axes of rotation of the printing form cylinder and of the impression cylinder can be varied and the printing form cylinder and the impression cylinder can be set against each other, to form a press nip in which a substrate can be printed. A first drive for producing a rotational movement of the printing form cylinder is connected to the printing form cylinder through a drive train. At least one component of the drive train has a torque axis running through the impression cylinder. A printing press having at least one printing unit and a process for producing labels or self-adhesive labels in a printing press, are also provided.
