Description

Vorrichtung zum Abstellen des Druckzylinders von dem Formzylinder bei Rotationstiefdruckmascbinen für Papierbahnen Bei den bekannten Rotationstiefdruckmaschinen zum Bedrucken von Papierbahnen zeigt sich der Nachteil, daß beim Abstellen des Druckzylinders von dem Formzylinder die Papierbahn entspannt wird. Dieses Abstellen und das nachfolgende Wiederanstellen führt zu Registerunterschieden, die insbesondere bei Mehrfarbendruckmaschinen die Güte des Druckes in sehr störender Weise beeinträchtigen. Wenn die Maschine wieder angelassen und der Druckzylinder wieder angestellt wird, so zeigt es sich, daß sich das Register verschoben hat.Device for parking the printing cylinder from the forme cylinder in rotogravure printing machines for paper webs in the known rotogravure printing machines for printing paper webs there is the disadvantage that when the printing cylinder is turned off the paper web is relaxed from the forme cylinder. This parking and the following Re-adjusting leads to register differences, which is especially true in multi-color printing machines affect the quality of the print in a very disturbing way. When the machine restarted and the pressure cylinder turned on again, it turns out that that the register has shifted.

Dieser Nachteil wird beim Gegenstand der Erfindung dadurch vermieden, daß bei der Bewegung, die der Druckzylinder beim Abstellen des Druckes ausführt, ein zweiter, die Papierbahn führender Maschinenteil in solcher Weise verstellt wird, daß die beim Drucken herrschende Spannung der Papierbahn aufrechterhalten wird. Dies kann man beispielsweise in der Weise erreichen, daß man gleichzeitig mit dem Druckzylinder einen zweiten Zylinder, über den die Papierbahn läuft, also etwa den Trocken- oder den Kühlzylinder in solcher Weise verstellt, daß die Papierbahn gespannt bleibt. Das Auftreten von Registerunterschieden wird hierdurch mit Sicherheit vermieden.This disadvantage is avoided in the subject matter of the invention by that with the movement that the pressure cylinder executes when the pressure is turned off, a second machine part leading the paper web is adjusted in such a way, that the tension prevailing during printing of the paper web is maintained. This can be achieved, for example, by simultaneously using the Printing cylinder a second cylinder over which the paper web runs, i.e. about the Adjusted drying or cooling cylinder in such a way that the paper web is stretched remain. This will definitely avoid the occurrence of register differences.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Der Druckzylinder a und der Heizzylinder b sind in exzentrischen Büchsen d bzw. c gelagert, die durch Stangen e miteinander verbunden sind, so daß beim Abheben des Druckzylinders a von dem Formzylinder g der Heizzylinder b zwangläufig mitbewegt wird, und zwar in solcher Weise, daß die Spannung der Papierbahn f die gleiche bleibt wie vorher.The drawing shows an embodiment of the invention. The printing cylinder a and the heating cylinder b are mounted in eccentric sleeves d and c, respectively, which through Rods e are connected to each other, so that when the pressure cylinder is lifted from a the forme cylinder g of the heating cylinder b is inevitably moved with it, namely in such Way that the tension of the paper web f remains the same as before.
