Description
Rakelvorrichtung für Tiefdruckrotationsmaschinen Zusatz zur Patentanmeldung M 41870 XII / 15 d (Auslegeschrift 1109 187) Die Erfindung betrifft eine Rakelvorrichtung für Tiefdruckrotationsmaschinen, bei welcher die Rakel auf dem Rakelbalken eingespannt und nahe der freien Abstreifkante an einem sich über die ganze Breite erstreckenden, in einer zur Rakel annähernd senkrechten Richtung zusammendrückbaren Widerlager abgestützt ist, wobei das Widerlager aus einem aufblasbaren Schlauch besteht, der in einer Vertiefung des oberen Rakelbalkens angeordnet ist, nach Patentanmeldung M 41870 XII / 15 d. Diese Maßnahme dient dazu, den Rakeldruck über die ganze Zylinderbreite gegenüber den bisher bekannten Ausführungen zu vergleichmäßigen.Squeegee device for rotogravure rotary presses Addendum to patent application M 41870 XII / 15 d (Auslegeschrift 1109 187) The invention relates to a squeegee device for rotogravure printing machines, in which the squeegee is clamped on the squeegee bar and close to the free wiping edge on one that extends over the entire width Squeegee approximately perpendicular direction compressible abutment is supported, the abutment consists of an inflatable tube which is arranged in a recess of the upper squeegee beam, according to patent application M 41870 XII / 15 d. This measure serves to equalize the squeegee pressure over the entire cylinder width compared to the previously known designs.
Bei sehr dünnen Rakelmessern ist es bei hohem Rakeldruck dabei nicht zu vermeiden, daß sich die Rakel nach unten durchbiegt. Um dies zu verhindern, wird gemäß der Erfindung der untere Rakelbalken mit einer Stütze versehen, welche auf der dem Schlauch gegenüberliegenden Seite des Rakelmessers anliegt. Damit kann nicht nur eine Ablenkung des Rakelmessers nach unten verhindert, sondern auch das Rakelmesser ohne Ausbau aus der Haltevorrichtung nachgeschliffen werden.In the case of very thin doctor blades, this is not the case if the doctor blade pressure is high to avoid that the squeegee sags downwards. To prevent this from happening, will according to the invention, the lower doctor beam provided with a support which on on the opposite side of the doctor blade from the hose. Can't do that only prevents downward deflection of the doctor blade, but also prevents the doctor blade be reground without removing from the holding device.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Hierbei zeigt Fig. 1 eine mit dem unteren Rakelbalken verschraubte Rakelstütze, Fig.2 eine mit dem unteren Rakelbalken aus einem Stück bestehende Rakelstütze.Exemplary embodiments of the invention are shown in the drawing. 1 shows a squeegee support screwed to the lower squeegee bar, 2 shows a squeegee support made of one piece with the lower squeegee bar.
In Übereinstimmung mit dem Hauptpatent (der Hauptpatentanmeldung) bezeichnet 1 den Formzylinder, 2 die Rakel, 3 und 4 den oberen bzw. unteren Rakelbalken, 5 die Abstreifkante und 6 den aufblasbaren Schlauch. Die Stütze 9 kann, wie aus der Fig. 1 ersichtlich ist, am unteren Rakelbalken 4 verschraubt sein. Sie kann aber auch aus einem Stück mit demselben bestehen, wie Fig. 2 zeigt.In accordance with the main patent (the main patent application), 1 denotes the forme cylinder, 2 the squeegee, 3 and 4 the upper and lower squeegee bars, 5 the wiping edge and 6 the inflatable tube. As can be seen from FIG. 1, the support 9 can be screwed to the lower doctor bar 4. But it can also consist of one piece with the same, as FIG. 2 shows.
