Description

Der Erfindungsgegenstand betrifft eine Verbesserung für die Lagerung der Feucht- oder der Farbwalzen einer lithographischen Rotationsmaschine. Die an sich bekannten Feucht-5 oder Farbwerke bestehen fast immer aus einer Verreibwalze α und zwei an diese angelehnte Feucht- oder Farbwalzen b. Die Verreibwalze α wird zwangsweise angetrieben und für die Verreibung seitlich hin und her hewegt. Die Farbe oder das Wasser wird durch geeignete Vorrichtungen auf die Verreibwalze α übertragen, und diese gibt Farbe oder Wasser an die Feucht- oder Farbwalzen b und an den Formzylinder c ab. Bei den meisten Anordnungen werden die Feucht- oder Farbwalzen b mittels Stellvorrichtung an die Verreibwalze α fest und an den Formzylinder c federnd angedrückt. Es besteht dabei der Nachteil, daß die unebenen Stellen der Farbwalzen mit Lederbezug oder der Feuchtwalzen mit Stortbezug bei starrem Andrücken der Feucht- oder Farbwalzen h an die Verreibwalze α würgen und klemmen und so eine einwandfreie Übertragung verhindern.The subject matter of the invention relates to an improvement for the storage of the dampening or inking rollers of a lithographic rotary machine. The dampening or inking units known per se almost always consist of a distribution roller α and two dampening or inking rollers b based on this. The distribution roller α is forcibly driven and moved back and forth to the side for the distribution. The ink or the water is transferred to the distribution roller α by suitable devices, and this transfers ink or water to the dampening or inking rollers b and to the forme cylinder c . In most arrangements, the dampening or inking rollers b are pressed firmly against the distribution roller α by means of an adjusting device and are pressed resiliently against the forme cylinder c. There is the disadvantage that the uneven areas of the inking rollers with leather cover or the dampening rollers with Stort cover choke and jam when the dampening or inking rollers h are pressed rigidly against the distribution roller and thus prevent proper transmission.

Der Gegenstand der vorliegenden Erfindung beseitigt diesen Nachteil, indem die Feuchtoder Farbwalzen federnd an die Reibwalze α und an den Formzylinder c unter Begrenzung durch verstellbare Anschläge angepreßt werden. Die Walzenträger d, die drehbar um die Reibwalze α gelagert sind, sind zweiteilig und , haben Scharniere mit dem Drehpunkt e und den Anschlägen f und g". Der Anschlag f dient zur Regelung der Anpressung an die Reibwalze α und der Anschlag g· zur Regelung der Anpressung an den Formzylinder c. Die Feder h zieht die Färb- oder Feuchtwalzen zu gleicher Zeit an die Verreibwalze α bzw. an den Anschlag/ und an den Formzylinder c bzw. an den Anschlag g. The object of the present invention eliminates this disadvantage in that the dampening or inking rollers are resiliently pressed against the distribution roller α and the forme cylinder c , limited by adjustable stops. The roller carriers d, which are rotatably mounted around the distribution roller α , are in two parts and have hinges with the pivot point e and the stops f and g ". The stop f is used to regulate the pressure on the distribution roller α and the stop g · for regulation the pressure on the forme cylinder C. The spring h pulls the inking or dampening rollers at the same time against the distribution roller α or against the stop / and against the forme cylinder c or against the stop g.

Die Scharnierhebel sind bei / und k geführt, um seitliche Erschütterungen zu vermeiden. Beim Abheben der Feucht- oder Farbwalzen vom Formzylinder drehen sich dieselben um die Verreibwalze a, ohne daß die federnde Anpressung gegen letztere außer Tätigkeit kommt.The hinge levers are guided at / and k to avoid lateral vibrations. When the dampening or inking rollers are lifted from the forme cylinder, they rotate around the distribution roller a without the resilient pressure against the latter becoming inoperative.
