Das durch die Zeichnung dargestellte Feuchtwerk für lithographische Druckmaschinen besteht der Hauptsache nach aus einem Wassergefäß /, einer Tauchwalze A, einem Abstreifer B, einer Walzenbürste G, einem Gehäuse N mit einem Schieber M. The dampening system for lithographic printing machines shown in the drawing consists mainly of a water container /, a fountain roller A, a scraper B, a roller brush G, a housing N with a slide M.
Der Antrieb der Walze A und der Bürste G geschieht durch ein Zahnrad E, welches auf einer Welle D sitzt. Das Zahnrad E greiftThe drive of the roller A and the brush G is done by a gear E, which sits on a shaft D. The gear E engages
ίο in die beiden Räder F und C ein und bewirkt dadurch eine gleichförmige gleichgerichtete Drehung der Tauchwalze A und der Bürste G. Durch Anordnung eines Überlaufrohres K wird der Wasserspiegel im Wassergefäß / immer konstante Höhe haben, wenn aus dem Wassergefäß H fortwährend Wasser nach / gepumpt wird. Bei gleichförmiger Drehung der Walze A und gleichmäßiger Eintauchtiefe derselben wird die Walze A immer dieselbe Wassermenge mit fortnehmen. Durch den Abstreifer B wird das überflüssige Wasser von der Walze A abgestreift, welches wieder in das Gefäß / zurückfließt. Um mehr oder weniger Wasser abstreifen zu können, ist der Abstreifer B radial gegen die Tauchwalze A einstellbar. Da die Bürste G und die Walze A sich in gleicher Richtung drehen, streift die Bürste das auf der Walze befindliche Wasser ab. In dem Augenblick, in dem die Bürstenhaare den Abstreifer B verlassen, schnellen dieselben aus der gebogenen Lage in ihre ursprünglich radiale Lage zurück und schleudern das daran befindliche Wasser tangential dunstförmig ab, das durch die Gehäuseöffnung auf die Druckplatte gelangt.ίο into the two wheels F and C and thereby causes a uniform, unidirectional rotation of the immersion roller A and the brush G. By arranging an overflow pipe K , the water level in the water container / will always have a constant height if water is continuously pumped into / from the water container H. will. With a uniform rotation of the roller A and a uniform immersion depth of the same, the roller A will always take away the same amount of water. The excess water is wiped off the roller A by the scraper B and flows back into the vessel /. In order to be able to wipe off more or less water, the wiper B can be adjusted radially against the dip roller A. Since the brush G and the roller A rotate in the same direction, the brush wipes off the water on the roller. At the moment when the brush hairs leave the scraper B , they snap back from the curved position to their original radial position and throw off the water attached to it tangentially in the form of a vapor, which passes through the housing opening onto the pressure plate.
Der Abstreifer B läßt sich außer radial zur Tauchwalze A auch in deren Drehrichtung und entgegengesetzt dazu verstellen. Durch diese Verstellbarkeit wird erreicht, daß die Bürstenhaare mehr oder weniger durchgebogen werden. Dieselben werden also beim Zurückschnellen mehr oder weniger Wasser abspritzen.The scraper B can be adjusted not only radially to the dip roller A, but also in the direction of rotation and in the opposite direction. This adjustability ensures that the brush hairs are more or less bent. They will therefore spray more or less water when they snap back.
Bei geschlossenem Schieber M fließt das abgespritzte Wasser in die Rinne L ab, durch die es seitlich abgeleitet wird. Je nachdem man den Schieber M längere oder kürzere Zeit offen hält, kann man größere oder kleinere Flächen dadurch befeuchten.When the slide M is closed, the sprayed water flows into the channel L , through which it is drained off to the side. Depending on whether the slide M is kept open for a longer or shorter period of time, larger or smaller areas can be moistened in this way.
