Abstract: A web-fed printing machine that is highly variable in terms of its configuration, provides a high degree of positioning accuracy of processing modules and has a cost-efficient machine frame, includes a plurality of the processing modules fixed to the machine frame. Each respective processing module is advantageously fixed to the machine frame by a respective carrier module. Every carrier module includes two parallel longitudinal beams extending in the machine direction and two parallel crossbars which are oriented at right angles to the longitudinal beams and which interconnect the two longitudinal beams.

Abstract: 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.

Abstract: A flexographic printing unit includes an engraved roll, a form cylinder and an impression cylinder. Axes of rotation of the engraved roll and the form cylinder are disposed in a horizontal plane and axes of rotation of the form cylinder and the impression cylinder are disposed in a vertical plane. The printing unit has at least one knee lever system for applying a pretensioning force to the form cylinder. A narrow web label printing press having at least one flexographic printing 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: An apparatus and a method are provided for cutting, cutting-out and perforating web or sheet substrates. The apparatus has a laser cutting device disposed above or below a transport plane for processing a substrate. The laser cutting device includes at least one laser array extending over the width of the substrate and having individually drivable lasers. The laser array is composed, in particular, of a plurality of individual arrays. The lasers are, in particular, constructed as vertical-cavity surface-emitting lasers. In this way, processing of the substrate at high transport speeds is made possible.

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.

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 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.
