Abstract

Verfahren zum Aufspannen einer Druckplatte auf einem Druckzylinder, entsprechende Spannvorrichtung, sowie da­ zugehoerige Druckplatte, wobei eine Vorrichtung Verwen­ dung findet, die geeignet ist, den Umfang des Druckzylinders zu verkleinern und unter Verwendung einer Druckplatte, die an ihren Enden angeformte Ausnehmungen aufweist, um eine formschluessige Verbindung der Plattenenden nach Aufwickeln der Platte auf dem Zylinder zu ermoeglichen, wo­ bei der Zylinder eine magnetische Halteeinrichtung aufweist, die an geeigneter Stelle des Zylindermantels vorgesehen ist und in Uebereinstimmung mit der magnetischen Haltevor­ richtung die zu verbindenden Enden der Druckplatte auf dem Zylindermantel zu liegen kommen, und der Zylinder eine Laengsausnehmung mit einer Spannvorrichtung aufweist, die aus einem radial beweglichen Bauteil besteht, dessen aeussere Flaeche eine Woelbung aufweist, die der Woelbung des Zylindermantels entspricht. Process for clamping a printing plate on a Printing cylinder, corresponding clamping device, and there associated pressure plate, using a device dung that is suitable, the circumference of the impression cylinder to zoom out and using a pressure plate that has recesses formed at their ends in order to a positive connection between the plate ends Wrapping the plate on the cylinder allows where in which the cylinder has a magnetic holding device, which is provided at a suitable point on the cylinder jacket and in accordance with the magnetic holding device direction of the ends of the pressure plate to be connected on the Cylinder jacket come to rest, and the cylinder one Has longitudinal recess with a clamping device, which consists of a radially movable component, the outer surface has a curvature that the curvature corresponds to the cylinder jacket.
