Abstract

Druckzylinder (1) fuer eine Rotationsdruckmaschine, bestehend aus einem rohrfoermigen, elastischen, duennen Mantel (12), der fest und abgedichtet mit den Enden des Zylinders verbunden ist, wobei der Zylinder Umfangskammern aufweist, die eine nicht komprimierbare Fluessigkeit (11) aufnehmen, mit Mitteln zum Verdraengen der Fluessigkeit, um somit den aeusseren Durchmesser des Druckzylinders zu vergroessern. Die Einrichtungen zum Verdraengen der Fluessigkeit bestehen aus einem Gewindestift (21), der in eine Leitung einschraubbar ist, die mit den die Fluessigkeit aufnehmenden Kammern in Wirkverbindung steht. Der Gewindestift steht mit einem koaxial angeordneten Kolben (20) in Wirkverbindung, der eine Druckkraft auf die Fluessigkeit in den Kammern uebertragen kann. Printing cylinder (1) for one Rotary printing machine consisting of one tubular, elastic, thin jacket (12) that is tight and sealed is connected to the ends of the cylinder, the cylinder Has peripheral chambers that have a non-compressible liquid (11) absorb, with means for displacing the liquid, thus to enlarge the outer diameter of the impression cylinder. The liquid displacement facilities consist of a grub screw (21) which is in a Cable can be screwed in with the the fluid-absorbing chambers are operatively connected. The The grub screw stands in with a coaxially arranged piston (20) Active connection, which is a compressive force on the liquid in the Can transfer chambers.

Die Aussenraender des Huellmantels weisen zwei seitliche Verdickungen (32, 40) auf, um eine Aufnahme oder einen Sitz fuer die aufzuspannende Druckplatte zu schaffen. Die Aufnahme hat eine Tiefe, die der Dicke der Druckplatte entspricht. In vorteilhafter Weise sind die aeusseren Kanten (33, 43) der Randverdickung abgerundet. Die Verdickungen koennen durch Bearbeiten des Mantels, z.B. durch Materialabnahme oder durch Materialauftrag hergestellt werden; in diesem Falle, in vorteilhafter Weise durch Auftrag eines gleichartigen Materials mit Eigenschaften, die aehnlich jenen der Druckplatte sind. The outer edges of the shell have two side thickenings (32, 40) to a seat or a seat for the to be clamped     To create pressure plate. The depth of the recording is that of the thickness corresponds to the pressure plate. The outer ones are advantageous Edges (33, 43) of the edge thickening rounded. The thickening can by working the jacket, e.g. through material acceptance or through Material order are manufactured; in this case, more advantageous Way by applying a similar material with properties, which are similar to those of the pressure plate.

Zur Aufnahme der Druckplatten, die aus gewickelten und endseitig zusammengefuegten Platten bestehen, weist der Mantel wenigstens einen Laengsschlitz auf, in dem der Verbindungsstoss der Druckplatte angeordnet und festgelegt ist. To accommodate the printing plates, which are wound and end-sided assembled plates exist, the jacket has at least one Longitudinal slot in which the connection joint of the pressure plate is arranged and fixed.
