PATENTAMPATENTAM

KLASSE IS: Druckerei.CLASS IS: Printing.

Bei der Vorrichtung des Haupt-Patentes zum Reinigen von Druckwalzen wurden dieselben nach dem Abbürsten, aber während des Rotirens, mittelst eines Messers abgeschabt, wobei die Messer nicht selten in die Walzenmasse einrissen.In the apparatus of the parent patent for cleaning pressure rollers, the same became after brushing, but while rotating, scraped off with a knife, whereby the knives often tore into the roller mass.

Um diesem Uebelstand abzuhelfen, geschieht das Abschaben der Walzen mittelst zweier parallel neben einander liegender bogenförmiger Messer / und Z1, Fig. 1, 2 und 4, deren abgerundete Kante, Fig. 5, sich senkrecht auf die Walze d legt. Die Messer sind, zur Walzenachse unter einem Winkel verstellt, an einem Arm m befestigt, welcher auf der abgerundeten Kante η des Maschinengestelles parallel zur Walzenachse verschiebbar und innerhalb gewisser Grenzen um η drehbar ist. Dieser Messerbock wird während des Rotirens der Druckwalze mit Hülfe des Handgriffes m\ auf der runden Kante η reitend, unter leichtem Druck die Walze entlang bewegt, wobei die schräge Stellung der Messer die Bewegung parallel zur Walzenachse wesentlich unterstützt. In order to remedy this inconvenience, the rollers are scraped off by means of two parallel curved knives / and Z 1 , FIGS. 1, 2 and 4, the rounded edge of which, FIG. 5, lies vertically on the roller d. The knives, adjusted at an angle to the roller axis, are attached to an arm m which is displaceable on the rounded edge η of the machine frame parallel to the roller axis and can be rotated about η within certain limits. While the pressure roller is rotating, this knife bracket is moved with the help of the handle m \ on the round edge η under light pressure along the roller, the inclined position of the knife significantly supporting the movement parallel to the roller axis.

Sind die Messer Z Z1 an einem Ende der Walze angelangt, so wird der Hebelarm m1 niedergedrückt und mit dem Arm m und den Messern an das entgegengesetzte Ende zurückgeführt. When the knives ZZ 1 have reached one end of the roller, the lever arm m 1 is pressed down and returned to the opposite end with the arm m and the knives.

Der Behälter k mit der die Druckerfarbe auflösenden Flüssigkeit wird ähnlich wie im Haupt-Patent beim Niederdrücken der Bürste e mit Hülfe der gegen den Deckel fl anstofsenden Stifte g, welche auf die kurzen Arme der in i drehbaren doppelarmigen Hebel ΥιΛ h2 drücken, gegen die Walze bewegt.The container k with the liquid dissolving the printing ink is similar to the main patent when the brush e is pressed down with the aid of the pins g, which press against the lid f l , which press on the short arms of the two-armed lever Υι Λ h 2 , which can be rotated in i, moved against the roller.
