Zur An- und Abstellung der Rasterwalze 4 relativ zur Farbauftragwalze 2 ist das Exzenterlager 7 mittels des Schalthebels 8 verdrehbar. An dem Schalthebel 8 ist ein Kniehebelgetriebe 9 mit einer Feder 10 angeordnet. Bei der Anstellbewegung wird über das Kniehebelgetriebe 9 die Feder 10 gespannt, deren Kraft wirkt über den Anlenkpunkt 11 und das Exzenterlager 7 verstärkt auf die Rasterwalze 4. Auf den Ballenenden der Farbauftragwalze 2 und der Rasterwalze 4 sind Schmitzringe angeordnet. Somit stützt sich die Rasterwalze 4 von der Federkraft getrieben und im Dreiringlager 5 geführt gegen die Farbauftragwalze 2 ab und kann kleinen Positionsänderungen der Farbauftragwalze 2 folgen, so - dass die Pressung zwischen Farbauftragwalze 2 und Rasterwalze 4 konstant bleibt.The inking roller 2 associated with anilox roller 4 is a three-ring bearing. 5 in the machine frame 6 - indicated in the drawing with slashes - stored.
