Description

Wenn die mit der lichtempfindlichen Schicht versehenen photographischen Druckplatten o. dgl. zwecks gleichmäßiger Verteilung der flüssig aufgetragenen Schicht geschleudert werden, besteht die Gefahr, daß abgeschleuderte überschüssige Teile der lichtempfindlichen Masse beim Auftreffen an die Innenwandung der Schleudervorrichtung zurückprallen und auf die Schichtseite der Platte gelangen, die dadurch unbrauchbar wird.When the photographic printing plates provided with the photosensitive layer or the like for the purpose of even distribution of the liquid applied layer there is a risk that excess parts of the light-sensitive parts are thrown off Mass bounce back when it hits the inner wall of the spinning device and get on the layer side of the plate, which makes it unusable will.

Um das zu verhüten, ist bereits vorgeschlagen worden, den Plattenträger der Schleudervorrichtung in der Ebene der Platte mit einem Auffangring in feste' Verbindung zu bringen, der im Querschnitt muldenförmig gestaltet ist. Durch, diesen muldenförmigen Auffangring wird aber die oben geschilderte Gefahr nicht völlig beseitigt, denn wenn beim Stillsetzen der Schleudervorrichtung die Wirkung der Zentrifugalkraft nachläßt, kann die in der Mulde angesammelte Masse überfließen und dann auf die Platte abtropfen und diese verderben.To prevent this, it has already been proposed that the plate carrier Throwing device in the plane of the plate with a catch ring in a fixed 'connection to bring, which is designed trough-shaped in cross-section. Through, this trough-shaped Orifice ring, however, does not completely eliminate the danger described above, because if the Stopping the centrifugal device decreases the effect of centrifugal force, the The mass that has accumulated in the well overflow and then drip onto the plate and this spoil.

Zur Vermeidung dieses Nachteils wird nach der Erfindung der Auffangring konisch gestaltet, und zwar so, daß er sich in Richtung der Rückseite der zu schleudernden Platte erweitert. Hierdurch wird erreicht, daß der von der Platte abgeschleuderte und von dem Ring aufgefangene Überschuß nach rückwärts abgelenkt und so aus dem Bereich der Schichtseite der Platte gebracht wird. Etwa vom Auffangring gegen die Gehäusewand geschleuderte Masse kann in diesem Falle auf die Schichtseite der Platte nicht zurückprallen,To avoid this disadvantage, the collecting ring is designed conically according to the invention, in such a way that it widens towards the rear of the plate to be thrown. This ensures that the excess thrown off the plate and caught by the ring backwards is deflected and thus brought out of the area of the layer side of the plate. Approximately Mass thrown by the collecting ring against the housing wall can in this case the layer side of the plate does not rebound,

sondern im ungünstigsten Falle ist nur damit zu rechnen, daß abgespritzte Masseteile auf die Rückseite der Platte gelangen, wo sie völlig unschädlich sind.but in the worst case it is only to be expected that sprayed mass parts on the back of the plate, where they are completely harmless.

Auf der Zeichnung ist in Abb. 1 und 2, im Querschnitt und von vorn gesehen, eine Schleudervorrichtung mit geneigt gelagertem Plattenhalter dargestellt, die Abb. 3 zeigt im Querschnitt die Schleudervorrichtung mit *5 waagerecht umlaufendem Plattenhalter. Der an der Welle« befestigte Plattenhalterb, auf dem die Plattet in bekannter Weise befestigt werden kann, wird von dem Auffangring g derart umschlossen, daß die beim raschen Umlauf des Halters b von der Plattet abgeschleuderte Masse von dem Ringg· aufgefangen wird. Wie die Abb. 1 und 3 erkennen lassen, ist der Auffangring konisch gestaltet, und zwar so, daß er sich in Richtung nach der Rückseite der Plattet hin erweitert, so daß etwa von ihm abgeschleuderte Masse nicht auf die Schichtseite der Plattet zurückspringen kann.1 and 2, seen in cross section and from the front, the drawing shows a centrifugal device with an inclined plate holder; Fig. 3 shows in cross section the centrifugal device with a horizontally rotating plate holder. The plate holder b fastened to the shaft , on which the plate can be fastened in a known manner, is enclosed by the collecting ring g in such a way that the mass thrown off the plate when the holder b rotates rapidly is caught by the ring g. As shown in Figs. 1 and 3, the collecting ring is conical in shape, in such a way that it widens towards the rear of the plate, so that any mass thrown off by it cannot jump back onto the layer side of the plate.
