摘要:
Ein Aufzug auf einer Mantelfläche einer Walze, z. B. einer Walze eines Druckwerks, weist eine elastische und/oderkompressible Schicht mit einer vom Grad einer Eindrückung abhängigen Flächenpressung auf. Die Schicht ist derart beschaffen, dass eine Abhängigkeit der Flächenpressung von der Eindrückung zumindest bereichsweise eine Steigung von weniger als 700 (N/cm 2 )/mm aufweist.

Bei einem Verfahren zur Druckvorbereitung eines Formzylinders (01) einer Druckmaschine wird der Anfang einer Druckform (04) auf der Mantelfläche (02) des Formzylinders festgelegt und die Druckform während einer Zylinderdrehung angedrückt. Bereits während des Aufbringvorganges wird die Druckform bebildert. Nach Gebrauch der Druckform kann diese vom Zylindermantel abgerakelt werden.
摘要:
Lens arrangements consisting of glass lenses are normally used to focus a laser beam exiting from a glass fiber in a divergent manner. Imaging on an offset printing plate occurs, for example, with the aid of laser beams, whereby the laser beams produced by laser diodes are conducted to the offset printing plate by means of glass fibers and focused onto the offset printing plate by lenses or lens arrangements in order to produce picture elements. In order to produce compact lenses or lens arrangements, a fresnel lens or a holographic lens is used.

The invention relates to printing groups comprising at least two cooperating cylinders, each of which is mounted in a bearing unit that radially displaces the respective cylinder. At least one bearing unit is provided with an actuator which is controlled or regulated by a control unit. An inking unit encompassing at least one ink applying roll is provided, at least one of the cylinders and an ink applying roll of the inking unit being optionally placed against each other, and/or a dampening unit comprising at least one moisture applying roll is provided, at least one of the cylinders and a moisture applying roll of the dampening unit being optionally placed against each other. The two ends of at least one ink applying roll of the inking unit and/or the two ends of the at least one moisture applying roll of the dampening unit are mounted in a support bearing that radially displaces the respective ink applying roll or moisture applying roll. The support bearings of the ink applying roll or the moisture applying roll are equipped with at least one actuator, respectively. Said at least one actuator of the support bearings and the at least one respective actuator of the bearing units are remote controlled. The at least one actuator of the bearing unit of the cylinders is embodied as a hydraulic actuator while the at least one actuator of the support bearings of the at least one ink applying roll or the at least one moisture applying roll is configured as a pneumatic actuator. The respective bearing unit of the cylinders is provided with a linear bearing which is guided based on linear elements. A peg embodied on one of the cylinders is rotatably mounted in the respective linear bearing while the linear elements of the respective linear bearing enclose a maximum angle of 15° along with a connecting line or plane that extends through the respective centers of rotation of the cylinders. The at least one actuator of the bearing unit displaces the respective linear bearing along the linear elements in a positioning direction oriented towards the printing material. The respective bearing unit is mounted on an inside of a frame wall of the printing group, said inside facing the respective cylinder.

Die Erfindung betrifft eine Vorrichtung zur Lagerung eines Zylinders (02, 03) einer Druckeinheit mit einem entlang eines Stellweges (S) in Linearlagern bewegbaren, ein Rotationslager (12) aufweisenden Lagerblock (16), wobei die Lagerung als Lagereinheit (06) in der Art einer als ganzes montierbaren Baueinheit ausgeführt ist, welche neben dem Rotationslager (12) beide die Relativbewegung des Lagerblockes (16) ermöglichenden zusammen wirkenden Lagerelemente (13, 14) umfasst.
摘要:
The invention relates to a printing group pertaining to a printing machine, comprising a pair of cylinders (02, 03, 07, 11) respectively having a circumference which corresponds essentially to the length of a section of a side to be printed. The effective generated surface of at least one of the cylinders comprises one break (04, 06) at the most, seen in the circumferential direction, but seen in the longitudinal direction, comprises a plurality of adjacently arranged breaks which, seen in the circumferential direction, are arranged in a staggered manner in relation to each other.
摘要:
The invention relates to a method for labeling an object according to which at least one microchip or one electromagnetically readable circuit is imprinted onto the object during production. An algorithm is implemented in the circuit by means of which information that is comprised by the object can be coded. The invention also relates to a method for verifying the authenticity of an object (01) that comprises an electromagnetically readable circuit (02) and information (C), so that the information (C) is coded both by means of the algorithm (A) that is implemented in the circuit (02) and in a read device (03) and the results (C'; C'') are subsequently compared to check that they are identical.

摘要:
Ein Druckwerk einer Druckmaschine weist mindestens zwei Zylinder, nämlich einen Formzylinder und einen Übertragungszylinder auf, wobei der Übertragungszylinder entlang eines linearen Stellweges wahlweise in Druck-An- und Druck-Ab-Stellung bringbar ist. Die beiden Zylinder sind mittels mindestens eines Antriebsmotors mechanisch unabhängig von einem anderen Druckwerk rotatorisch antreibbar, wobei der Antriebsmotor gestellfest angeordnet ist.
