 die vom Farbwerk 12-15 kommende Farbe. Die Rüttelwalze 16 bewirkt durch ihre gegenläufige Bewegung und die beispielsweise durch eine Rillenkurve und einen Stein eingeleitete axiale Bewegung ein vollkommenes Einfärben der Bildplatte 3 derart, dass alle Vertiefungen der Druckform wirklich mit Farbe gefüllt werden. Darauf treten die Wischer in Tätigkeit. Beim ersten Vorbeigang der Druckform an den ortsfesten Wischern   17 und 18 wischen   diese die überschüssige Farbe vom Druckblech 3 ab, der Wischer 19 ist dagegen abgehoben, also ausser Tätigkeit gesetzt.

   Während des nun folgenden zweiten Vorbeiganges der   Druckform   3 sind die Auftragwalze 15 und die Rüttelwalze 16 abgehoben, um ein nochmaliges Einfärben zu vermeiden. Hingegen erfolgt durch die   Wischvorriehtungen   17 und 18 mittels des inzwischen   weitergeschalteten   frischen Wischtuches ein nochmaliges Abwischen der Druckplatte. Beim Auftreffen auf den nunmehr angestellten Wischer 19, den sogenannten nassen Polierwischer, wird die Oberfläche des   Bildbleches   3 von den letzten Spuren der Farbe gereinigt. 



   Anschliessend erfolgt der Abdruck der in den Vertiefungen des Bildbleches 23 sitzenden Farbe auf den vom Druckzylinder   4   herangeführten Druckbogen. Die Ausführung geschieht in bekannter Weise. 



   Statt des halbgrossen Plattenzylinders kann auch ein Plattenzylinder Verwendung finden, der den gleichen Durchmesser hat wie der Druckzylinder 4. In diesem Falle wird der Druckzylinder, ähnlich wie bei den bekannten   Hochdruck-Zweitourenschnellpressen, rhythmisch   abhebbar vom Plattenzylinder gesteuert. 



   PATENT-ANSPRÜCHE :
1. Rotationstiefdruckmaschine zum Drucken von   Stahl-oder Kupferstichplatten   mit elastischen und selbsttätig arbeitenden Wischern, dadurch gekennzeichnet, dass der Plattenzylinder (1), der beispielsweise in bei Rastertiefdruckmaschinen bekannter Weise nur den halben Durchmesser des Druckzylinders   (4)   hat und mit diesem in dauerndem Eingriff steht, vor dem Drucken einmal mit Farbe versehen, dagegen zweimal an den   Wischvorrichtungen   (17, 18, 19) vorbeigeführt wird.

 the color coming from the inking unit 12-15. The vibrating roller 16 effects, through its counter-rotating movement and the axial movement initiated, for example, by a groove curve and a stone, a complete inking of the image plate 3 in such a way that all the depressions in the printing form are really filled with color. The wipers then come into action. When the printing forme passes the stationary wipers 17 and 18 for the first time, these wipe off the excess ink from the printing plate 3, while the wiper 19, on the other hand, is lifted off, that is, it is inactive.

   During the second passage of the printing forme 3, which now follows, the application roller 15 and the vibrating roller 16 are lifted off in order to avoid repeated inking. On the other hand, the wiping devices 17 and 18 cause the printing plate to be wiped again by means of the fresh wiping cloth which has meanwhile been switched on. When it hits the wiper 19, which is now employed, the so-called wet polishing wiper, the surface of the image sheet 3 is cleaned of the last traces of paint.



   The ink sitting in the depressions of the image plate 23 is then printed onto the printed sheet fed by the printing cylinder 4. The execution takes place in a known manner.



   Instead of the half-size plate cylinder, a plate cylinder can also be used which has the same diameter as the impression cylinder 4. In this case, the impression cylinder is controlled rhythmically liftable from the plate cylinder, similar to the known high-pressure two-speed high-speed presses.



   PATENT CLAIMS:
1. Rotogravure printing machine for printing steel or copperplate engraving plates with elastic and automatically operating wipers, characterized in that the plate cylinder (1), which is only half the diameter of the printing cylinder (4), for example in a manner known from gravure printing machines, and is in permanent engagement with it is provided with color once before printing, but is moved past the wiping devices (17, 18, 19) twice.

 

Claims (1)

2. Rotationstiefdruckmaschine nach Anspruch 1, dadurch gekennzeichnet, dass die vom Plattenzylinder zuerst überlaufenen Wischvorrichtungen (17, 18) örtlich fest, dagegen die zuletzt überlaufene Wischvorrichtung (19) rhythmisch abhebbar angeordnet sind. EMI2.1 2. Rotogravure printing machine according to claim 1, characterized in that the wiping devices (17, 18) overflown first by the plate cylinder are fixed in place, whereas the wiping device (19) overflowing last are arranged to be rhythmically liftable.
