Die Erfindung betrifft eine Feuchtmittelwalze für ein Feuchtwerk einer Offset-Rotationsdruckmaschine entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a dampening roller for a dampening unit of an offset rotary printing press according to the preamble of claim 1.
Durch die DE-OS 14 36 542 ist eine von einem Plattenzylinder mittels Reibschluß antreibbare, einen elastischen überzug aufweisende Feuchtmittelauftragwalze bekannt. Diese Feuchtmittelauftragwalze weist beidendig an ihrem Umfang ringförmig angeordnete Widerlager auf, die sich in rollbarem Kontakt zu beidendig am Umfang des Plattenzylinders angeordneten ringförmigen Auflagern befinden.DE-OS 14 36 542 is one of one Plate cylinder driven by friction, one dampening solution applicator roller with elastic coating known. This dampening solution applicator roller has both ends abutments arranged in a ring on its circumference, who are in rolling contact at both ends of the circumference of the Plate cylinder arranged annular supports are located.
Nachteilig bei diesem Antrieb ist, daß sowohl die Ringe des Widerlagers als auch der elastische überzug der angetriebenen Feuchtmittelauftragwalze aus unterschiedlichen Materialien bestehen. Weiterhin ist nachteilig, daß die an den Enden des Plattenzylinders befindlichen ringförmigen Auflager infolge der aufgespannten Druckplatten sowohl gegenüber dem Plattenzylinder einen größeren Durchmesser aufweisen als auch aus einem anderen Material bestehen.The disadvantage of this drive is that both the rings of the abutment as well as the elastic coating of the driven dampening roller different materials. Still is disadvantageous that the at the ends of the plate cylinder located annular supports as a result of clamped printing plates both against the Plate cylinders have a larger diameter than also consist of another material.
Die US 51 91 835 A beschreibt ein Feuchtwerk einer Rotationsdruckmaschine mit vier Feuchtwalzen. Eine direkt mit dem Formzylinder zusammenwirkende Feuchtmittelauftragwalze ist reibschlüssig angetrieben, während die dieser Feuchtmittelauftragwalze vorgeschalteten Feuchtittetwalzen formschlüssig mittels Zahnrädern angetrieben werden.US 51 91 835 A describes a dampening system Rotary printing machine with four dampening rollers. A interacting directly with the forme cylinder Dampening roller is frictionally driven, while that of the dampening roller upstream dampening rollers with a positive fit Gears are driven.
Die DE-AS 17 61 245 und die US 50 33 376 A offenbaren jeweils eine Feuchtmittelwalze, deren Ende mit einem Treibring versehen ist. Der Treibring und der Ballen der Feuchtmittelwalze weisen gleichen Durchmesser auf.DE-AS 17 61 245 and US 50 33 376 A disclose one dampening roller each, the end of which with a Drive ring is provided. The drift ring and the bale of the The dampening roller has the same diameter.
Die US 52 22 434 A beschreibt eine Farb- und Feuchtmittelwalze, die spindelartige Nuten zum Transport von Farbe bzw. Feuchtmittel aufweist.The US 52 22 434 A describes a color and Dampening roller, the spindle-like grooves for transport of ink or dampening solution.
Der Erfindung liegt die Aufgabe zugrunde, eine Feuchtmittelwalze zu schaffen, welche von einer im Feuchtwerk an beliebiger Stelle befindlichen Walze reibschlüssig antreibbar ist.The invention has for its object a Dampening roller too create one from any in the dampening system to any Location roller is frictionally driven.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1 solved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß die Feuchtmittelwalze über ihre gesamte Oberfläche einen gleichmäßigen elastischen überzug aufweist, bei welchem beidendig infolge eines "Einstiches" Treibringe kostengünstig ausgebildet werden können. Somit sind keine zusätzlichen Widerlager erforderlich. Die Feuchtmittelwalze ist mit ihren Treibringen an jede mit harter Oberfläche versehene Walze des Feuchtwerkes anstellbar und von dieser antreibbar, ohne daß dafür zusätzliche Auflager erforderlich sind. Besonders vorteilhaft ist die erfindungsgemäße Feuchtmittelwalze an eine changierende, d. h. in axialer Richtung hin- und herbewegbare angetriebene Feuchtreibwalze anstellbar.The advantages that can be achieved with the invention exist especially in that the dampening roller over their entire surface a uniform elastic Has coating, in which both ends due to a "Puncture" drive rings can be formed inexpensively can. So there are no additional abutments required. The dampening roller is with their Driving rings on any hard surface Roller of the dampening system adjustable and by this drivable without additional supports required are. This is particularly advantageous dampening solution roller according to the invention to an iridescent, d. H. axially reciprocable driven dampening roller adjustable.
Vorteilhaft ist, daß mit gleichem Durchmesser von Ballen und Treibringen gleiche Abwicklungsverhältnisse, d. h. gleiche Umfangsgeschwindigkeiten erzielt werden können.It is advantageous that the same diameter of bales and drive rings equal settlement ratios, d. H. same peripheral speeds can be achieved.
Nach einer vorteilhaften Ausführungsvariante weisen die Treibringe ein feuchtmittelabführendes Profil auf. Dies kommt insbesondere dann zum Einsatz, wenn im Feuchtmittelverlauf vor den Feuchtmittelauftragwalzen eine changierende Chromwalze angeordnet ist. Somit ist bei guter Friktion der Feuchtmittelauftragwalze über die Treibringe ein gleichmäßiger Feuchtmittelauftrag über die feuchtmittelführende Breite der Feuchtmittelauftragwalze gegeben.According to an advantageous embodiment, the Driving rings have a dampening agent-draining profile. This is used in particular when Dampening solution flow before the dampening solution application rollers an iridescent chrome roller is arranged. So is with good friction on the dampening roller Drive rings over an even dampening solution the width of the dampening solution Given dampening roller.

Die Arbeitsweise der erfindungsgemäßen Feuchtmittelwalze
ist wie folgt: Der Sprühbalken 3 überträgt das
Feuchtmittel auf die Chromwalze 4 über die Arbeitsbreite
b11 + c. Dabei bleibt an beiden Enden
der Chromwalze 4 jeweils ein über die Arbeitsbreite
b11 + c hinausgehender Bereich d trocken bzw. mit nur
wenig Feuchtigkeit versehen, so daß die Chromwalze 4
ihren Antrieb über die Treibringe 17; 18 der
Feuchtmittelübertragwalze 6 erhält. Die
Feuchtmittelübertragwalze 6 erhält von der Chromwalze 4
Feuchtmittel und gibt dieses an die changierende

Treibringe 17; 18 mit einem feuchtmittelabführenden
Profil zu versehen. Ein feuchtmittelabführendes Profil
19 kann z. B. aus auf dem Mantel der Treibringe 17; 18
schraubenförmig umlaufenden Nuten 21 bestehen, welche
das Feuchtmittel in Richtung der Enden von der
Feuchtmittelwalze 6; 8 wegtransportieren. Because of the axial stroke of the spray bar 3rd
