Abstract

Ein Feuchtwerk (4) für eine Druckmaschine (1) besteht aus einer ersten Walze (6) und einer zweiten Walze (7), die zusammen einen Schlupfspalt (N6,7) bilden.A dampening unit (4) for a printing press (1) consists of a first roller (6) and a second roller (7), which together form a slip gap (N 6, 7 ).

Das Feuchtwerk (4) zeichnet sich dadurch aus, daß eine Drehachse (14), um welche die erste Walze (6) an die zweite Walze (7) schwenkbar gelagert ist, auf einer Linie (L) liegt, welche durch eine Mittelachse (M) der ersten Walze (6) und im Wesentlichen parallel zu einer durch den Schlupfspalt (N6,7) verlaufenden Tangentiallinie (t6,7) verläuft.

Figure 00000001
The dampening unit (4) is characterized in that an axis of rotation (14), about which the first roller (6) is pivotably mounted on the second roller (7), lies on a line (L) which is defined by a central axis (M ) of the first roller (6) and essentially parallel to a tangential line (t 6.7 ) running through the slip gap (N 6.7 ).
