Abstract

Die Erfindung betrifft eine Dichtungsanordnung (1) für ein Feuchtwerk (F) an einer Offset-Druckmaschine mit einer Feuchtauftragwalze (7) und einer Dosierwalze (6), die derart aufeinder abrollen, daß mit dem oberen Zwik­ kel zwischen der Dosierwalze (6) und der Auftragwalze (7) eine einen Feuchtmittelvorrat aufnehmende Rinne (5) gebildet ist, mit einer Dichtungshalterung (3), die an einem Seitenteil (8) des Feuchtwerks (F) halterbar ist und einem in diese aufgenommenen Dichtelement (2), wobei die Dichtungshalterung (3) zur Stirnseite der Walzen hin vorgespannt ist, und wobei das Dichtelement (2) auf der Dosierwalze (6) radial aufliegend und an der Feuchtauf­ tragwalze (7) stirnseitig anliegend abdichtet. Um eine sichere Abdichtung der den Feuchtmittelvorrat aufnehmen­ den Rinne und zugleich ein bedienungsfreundliches Aus­ wechseln des Dichtelementes zu ermöglichen, ist vorgese­ hen, daß die Dichtungshalterung (3) einen Schwenkweg (x) für das Dichtelement (2) in eine Entnahme-Bereitschafts­ stellung freiläßt, in welche Stellung das Dichtelement (2) durch ein Drehen desselben um die Dosierwalze (6) schwenkbar ist. The invention relates to a sealing arrangement (1) for a dampening system (F) on an offset printing press a dampening roller (7) and a metering roller (6), which roll on each other in such a way that with the upper Zwik between the metering roller (6) and the application roller (7) a channel (5) receiving a dampening solution supply is formed, with a seal holder (3) on a side part (8) of the dampening unit (F) can be held and a sealing element (2) accommodated therein, wherein the seal holder (3) towards the end of the rollers is biased, and wherein the sealing element (2) on the Metering roller (6) lying radially and on the damp Carrying roller (7) seals against the face. To one Secure sealing of the dampening solution supply the gutter and at the same time a user-friendly exit To enable changing the sealing element is provided hen that the seal holder (3) has a swivel path (x) for the sealing element (2) in a readiness for removal position leaves in what position the sealing element (2) by rotating it around the metering roller (6) is pivotable.
