Das Hauptpatent 421242 bezieht sich auf ein \rerfahren zum Überziehen von lithographischen und ähnlichen Druckplatten mit einer lichtempfindlichen Schicht in einem geschlossenen Raum, bei dem die mit schädlichen Dämpfen geschwängerte Luft aus dem geschlossenen Raum abgesaugt und in ein Wasserbad gedrückt wird. Nach der Zusatzerfindung wird der Saugraum des Kompressors, der die zum Aufspritzen des Schichtmaterials notwendige Preßluft schafft, mit dem mit schädlichen Dämpfen geschwängerten Raum verbunden, und zwar derart, daß die aus dem Gehäuse abgesaugte Luft, bevor sie in den Kompressor gelangt, durch das Wasserbad hindurchgedrückt und dort gereinigt wird.The main Patent 421242 refers out for the coating of lithographic and other similar printing plates having a photosensitive layer in a confined space, wherein the laden with noxious vapors air from the closed space aspirated and is pressed into a water bath to a \ r. According to the additional invention, the suction space of the compressor, which creates the compressed air necessary for spraying the layer material, is connected to the space impregnated with harmful vapors, in such a way that the air sucked out of the housing, before it enters the compressor, passes through the water bath is pushed through and cleaned there.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung, und zwar stelltThe drawing shows an embodiment of the invention, namely represents
ao Abb. ι die Vorrichtung in Seitenansicht dar.ao Fig. ι the device in side view represent.
Abb. 2 zeigt das Wasserbad im Schnitt.
Die Trommel a, auf der die mit dem lichtempfindlichen Überzug zu versehende Platte
aufgespannt ist, läuft während des Aufspritzens in dem geschlossenen Gehäuse. b, c ist die Spritzvorrichtung, durch die die
lichtempfindliche Schicht auf die Platte aufgebracht wird, d ist der Kompressor, der die
zum Spritzen erforderliche Preßluft liefert. An die Saugseite des Kompressors ist ein
Rohr e angeschlossen, das unmittelbar über dem Wasserbad / endigt. Ein zweites Rohr g
-endigt in dem Wasserbad f\ das andere ist mit dem geschlossenen Raum b verbunden.
In dem Wasserbad / befinden sich Filter h, die zur Reinigung der Luft dienen. Die Luft
wird nun aus dem geschlossenen Gehäuse b abgesaugt, tritt durch -das- Wasserbad f hindurch
und wird durch das Rohr e dem Saugraum des Kompressors, zugeleitet.- Durch die
Erfindung wird die Anordnung einer beson- ■ deren Pumpe, die die aus dem Gehäuse abgesaugte
Luft in das Wasserbad drückt, vollständig erspart. Steht in dem Druckraum ein anderer Kompressor zur Verfügung, so läßt
sich dieser in gleicher Weise zur Absaugung der Luft verwenden,Fig. 2 shows the water bath in section.
The drum a, on which the plate to be provided with the photosensitive coating is clamped, runs in the closed housing during spraying. b, c is the spray device through which the photosensitive layer is applied to the plate, d is the compressor which supplies the compressed air required for spraying. A pipe e is connected to the suction side of the compressor and ends directly above the water bath /. A second tube in the water bath g -endigt f \ the other is connected with the closed space b. In the water bath / there are filters h which are used to purify the air. The air is now sucked out of the closed housing b , passes through the water bath f and is fed through the pipe e to the suction chamber of the compressor Housing presses extracted air into the water bath, completely saved. If another compressor is available in the pressure chamber, it can be used in the same way to extract the air,
