Definitions
- the invention relates to a dampening system for an offset printing press, that with a plate cylinder carrying a printing form and an inking unit in functional connection is after the Preamble of the main claim.
- a dampening unit of this type is known from DE 34 16 845 A1, which essentially consists of a feed device for the Dampening solution, a device for dosing the dampening solution film and a dampening roller that covers the dampening solution film transfers to a plate cylinder.
- the dampening system is with an inking unit assigned to the plate cylinder coupled as well as operated separately.
- the dampening roller is to the plate cylinder with different peripheral speed operable, so that for example foreign particles eliminating wiping effect.
- a dampening system which a ink-absorbing roller (rider roller) of the dampening roller in Has assigned contact.
- This ink-absorbing roller rotates with a different one to the plate cylinder Peripheral speed and is to the neighboring inking unit coupled or can be operated separately with the dampening roller.
- the disadvantage here is that abrasion occurs on the wiper that contaminates the dampening solution.

Abstract
Description
Beispielsweise liegt bei einer Feuchtauftragwalze nach der Farbspaltung (Auftrennen der Farbschicht) in einer Kontaktzone mit einem Plattenzylinder durch Abreißen von Farbe, insbesondere beim fadenförmigen Abreißen, keine gleichmäßige Farbverteilung über die Walzenbreite betrachtet vor, sondern eine unebene Oberflächentopographie der, beispielsweise auf die Feuchtauftragwalze vom Plattenzylinder, zurückgespalteten Restfarbe vor.
Ein weiterer Vorteil ist darin begründet, dass durch die verbesserte Benetzung der Feuchtwerkswalzen eine Reduzierung von Feuchtmittelzusätzen, beispielsweise von Isopropanol, realisierbar ist.
Ebenso ist durch den Einsatz von Plattiereinrichtungen die Bildung von Farbnebel spürbar reduziert.
Die Ausbildung der Plattiereinrichtung ist nicht auf eine oder mehrere mechanische Plattiereinrichtung(en) mit einem oder mehreren Plattierelement(en) beschränkt. Beispielsweise ist zur Erzielung einer ebenen Oberflächentopographie der Farbe mittels einer auf eine Feuchtwerkswalze gerichteten Blasvorrichtung eine Blasluft auf die Mantelfläche der farbführenden Feuchtwerkswalze oder ein auf die Mantelfläche der farbführenden Feuchtwerkswalze gerichtetes Ultraschallschwingsystem einsetzbar.

In einer Weiterbildung ist in Drehrichtung der Feuchtauftragwalze 5 nach der Kontaktzone 13 mit der ersten Reiterwalze 9 eine zweite Reiterwalze 10 nachgeordnet, welche wiederum in einer Kontaktzone 13 mit der Feuchtauftragwalze 5 in Funktionsverbindung ist. Je nach Ausbildung des Feuchtwerkes 4 sind weitere Kontaktzone 13 zwischen weitern Feuchtwerkswalzen vorhanden. So ist bei einer Ausbildung gemäß dem vorliegenden Beispiel eine Kontaktzone 13 auch zwischen der Dosierwalze 7 und dem Feuchtduktor 6 vorhanden. In dieser Ausbildung ist bei Bedarf auch in Drehrichtung der Dosierwalze 7 nach der Kontaktstelle 13 eine Plattiereinrichtung 15 an die Mantelfläche der Dosierwalze 7 anstellbar angeordnet.
In einer weiteren Ausbildung ist zusätzlich eine Plattiereinrichtung 15 der Feuchtauftragwalze 5 in Drehrichtung nach der Kontaktzone 13 mit der Feuchtmittelzuführung 12 und vor der Kontaktzone 13 mit dem Plattenzylinder 1 anstellbar angeordnet.
In einer weiteren Ausbildung führt das Plattierelement 17 tangential in Drehrichtung der Feuchtauftragwalze 5 geringfügig über deren Mantelfläche hinaus, wobei ein Abreißen von Farbe zu vermeiden ist.
In einer weiteren Ausbildung endet das freie Ende des Plattierelementes 17 in einem geringfügigen Abstand zur Mantelfläche der jeweiligen Feuchtwerkswalze 5,6,7,9,10.
Damit ist der Einsatz einer Plattiereinrichtung 15 ist nicht auf eine Feuchtauftragwalze 5 beschränkt. Vielmehr ist die Anordnung von Plattiereinrichtungen 15 auch an weiteren Walzen 6,7,9,10 des Feuchtwerkes 4 realisierbar, so dass in Drehrichtung einer feuchtmittelführenden Feuchtwerkswalze 5,6,7,9,10 nach einer Kontaktzone 13 in der ein Abreißen von Farbe oder eine Farbspaltung erfolgt ist, zumindest eine Plattiereinrichtung 15 an die Mantelfläche der Feuchtwerkswalze 5,6,7,9,10 parallel anstellbar ist.
Ebenso ist in Drehrichtung der entsprechenden Feuchtwerkswalze 5,6,7,9,10 die Plattiereinrichtung 15 in ihrer Richtung tangentenförmig oder sekantenfömig an die Mantelfläche der Feuchtwerkswalze 5,6,7,9,10 anstellbar angeordnet ist.
Nach der Kontaktzone 13 liegt die Restfarbe als unebene Oberflächentopographie in Form von Farbspitzen, Farbkuppen sowie Farbtälern auf der Mantelfläche der Feuchtauftragwalze 5 vor. In Drehrichtung der Feuchtauftragwalze 5 ebnet die Plattiereinrichtung 15 vor der Feuchtmittelzuführung 12 die aus dem Abriss entstandene unebene Oberflächentopographie der zurückgespalteten Farbe (Restfarbe) ein.
Die Feuchtauftragwalze 5 passiert nun in Drehrichtung die Kontaktzone 13 der Feuchtmittelzuführung 12. Da durch den Walzenkontakt in dieser Kontaktzone 13 eine erneute Farbspaltung (Farbabriss) erfolgt, ist bevorzugt nach der Feuchtmittelzuführung 12 und vor der Kontaktzone 13 mit dem Plattenzylinder 1 zusätzlich eine weitere Plattiereinrichtung 15 in Drehrichtung der Feuchtauftragwalze 5 anstellbar angeordnet. In einer weiteren Ausbildung ist zusätzlich in Drehrichtung der Feuchtauftragwalze 5 vor der Feuchtmittelzuführung 12 eine Plattiereinrichtung 15 anstellbar angeordnet. Dies ist insbesondere sinnvoll, wenn in Drehrichtung der Feuchtauftragwalze 5 vor der Kontaktstelle 13 der Feuchtmittelzuführung 12 zumindest eine Reiterwalze 9 und/oder 10 angeordnet ist. In der Kontaktstelle 13 der jeweiligen Reiterwalze 9, 10 erfolgt ebenso ein Farbabriss, so dass wiederum eine unebene Oberflächentopographie entstehen kann, die bevorzugt vor der Feuchtmittelzuführung 12 geebnet sein sollte.
