Abstract

In einem Feuchtwerk (102) einer Offsetdruckmaschine ist eine Zwischenwalze (108) zwischen dem Druckwerk (103) und den Feuchtwerkswalzen (105, 106) angeordnet, um mehrere Schlupf-Spalte (111, 109, 110) zu schaffen. Indem die Zwischenwalze (108) mit einer Oberflächengeschwindigkeit (Vintermed ) angetrieben wird, die höher als die Geschwindigkeit (Vdamp ) der Feuchtwerkswalzen (105, 106) und geringer als die Geschwindigkeit (Vpress ) des Druckwerks (103) ist, kann das Geschwindigkeitsverhältnis in jedem Schlupf-Spalt verringert werden.
