Bei Tiefdruckmaschinen ist es bekannt, anIn gravure printing machines, it is known to

Stelle eines vollen kupfernen Druckzylinders dünne Kupferplatten zu verwenden, die um einen vollen Kern oder um auf diesem Hegende auswechselbare Blöcke gespannt werden.Place a full copper printing cylinder using thin copper plates that are around a full core or to be stretched around on these interchangeable blocks.

Auf diese Art von Plattenzylindern bezieht sich die Erfindung, deren Gegenstand die besondere Anordnung zum Nachspannen der Druckplatten bildet. Zu diesem Zweck sindThe invention relates to this type of plate cylinder, the subject matter of which is particular Forms arrangement for re-tensioning the printing plates. To this end are

• beiden Scheiben samt der Klemmschiene mittels Schlitzführungen und Klemmschrauben nach Bedarf um die Zylinderachse verdreht werden können. Auf diese einfache Weise ist jederzeit eine vollkommen gleichmäßige Spannung der Druckplatte möglich. Die Zeichnung erläutert den Erfindungsgegenstand in einem Ausführungsbeispiel, durch Abb. ι schematisch in Seitenansicht der Gesamtanordnung, Abb. 2 in größerem Maßstab in Seitenansicht und Abb. 3 in Endansicht.• both panes including the clamping rail by means of slotted guides and clamping screws can be rotated around the cylinder axis as required. In this simple way a completely even tensioning of the pressure plate is possible at any time. the Drawing explains the subject matter of the invention in an exemplary embodiment Fig. Ι a schematic side view of the overall arrangement, Fig. 2 on a larger scale in side view and Fig. 3 in end view.

Der mit dem Druckzylinder α zusammenarbeitende Zylinder ist in an sich bekannter Weise als Plattenzylinder ausgebildet und besteht aus dem runden Kern b, auf welchem Blöcke c als Unterlage für die Kupferplatten d auswechselbar und in der Längsrichtung verstellbar befestigt werden können. Zu diesem Zweck besitzt der Zylinderkern b eine Führungsnut e, in welche eine entsprechend gestaltete Führungsleiste / der Blöcke c hineinpaßt, mittels welcher letztere an die jeweils gewünschte Fläche für den Abdruck eingestellt werden können.The cylinder cooperating with the printing cylinder α is designed in a manner known per se as a plate cylinder and consists of the round core b, on which blocks c can be attached as a base for the copper plates d, interchangeably and adjustably in the longitudinal direction. For this purpose, the cylinder core b has a guide groove e into which a correspondingly shaped guide bar / blocks c fits, by means of which the latter can be adjusted to the desired area for the impression.

Die Druckplatten d werden an dem einen Ende des jeweils verwendeten Blockes c mittels einer Klemmleiste g starr befestigt und am anderen Ende desselben durch eine verstellbar gelagerte Klemmschiene h nachspannbar angebracht.The pressure plates d are rigidly attached to one end of the block c used in each case by means of a clamping strip g and are attached to the other end of the same so that they can be tightened by an adjustably mounted clamping rail h.

Für diesen Zweck ist gemäß der Erfindung die Klemmschiene h in zwei seitlich auf der Zylinderachsei lose drehbaren Scheiben k drehbar gelagert, die an den Stirnwänden des Zylinders b mittels Schlitzführungen m und Stellschrauben» in der jeweiligen Lage festgestellt werden können, in welche sie durch gegen die der Schienet zunächst liegende Endfläche des Blockest wirkende, in der Schiene h angeordnete Spannschrauben 0 eingestellt werden können. Die Farbabgabe an die Druckplatte d erfolgt in üblicher Weise durch Farbwalzen p nebst Farbkasten q undFor this purpose, according to the invention, the clamping rail h is rotatably mounted in two laterally loosely rotatable disks k on the cylinder axis i , which can be fixed in the respective position on the end walls of the cylinder b by means of slot guides m and adjusting screws »in which they are by against the end face of the block, which is initially located on the rail and which is arranged in the rail h , of the clamping screws 0 can be adjusted. The ink is transferred to the printing plate d in the usual way by means of ink rollers p together with ink fountains q and

das Abstreifen der überflüssigen Farbe durch die übliche Rakel r.the scraping off of the superfluous ink with the usual squeegee r.
