Description
Verfahren zum Überziehen von Druckwalzen mit lichtempfindlichen und andern_Lösungen. Die Erfindung bezweckt die Anwendung des zum Überziehen zylindrischer Körper an sich bekannten Spritzverfahrens zum Über ziehen von Druckwalzen jeder Grösse und aus jedem Material, z. B. aus Metall, Gummi, Glas, Papier, mit lichtempfindlichen oder an dern Lösungen, z. B. mit Lösungen von Har zen, Albumin, Leim, Farben, in schwer oder leicht flüchtigen Ölen oder in Flüssigkeiten spirituoser oder wässeriger Natur.
Dieses Verfahren ermöglicht die Herstellung von gleichmässigen, zusammenhängenden oder von durchbrochenen, also Punkt- und Kornmanier aufweisenden Schichten, welche sich ohne weiteres zur photomechanischen Weiterbe handlung eignen.
Die Ausführung des Verfahrens geschieht zum Beispiel wie folgt: Die mit der Schicht irgendeiner Art zu versehende Druckwalze wird horizontal der artig angeordnet, dass sie von Hand oder maschinell um ihre Achse gedreht werden kann. Die für die Schicht bestimmte Lösung wird in einem Zerstäuber irgendeines Systems gefüllt.
Die Druckwalze wird nun in Umdrehung gesetzt und der in Tätigkeit gesetzte Zer stäuber entweder von Hard oder maschinell in kürzerer oder grösserer Entfernung in hori zontaler Richtung an der Druckwalze entlang geführt.
Die Ausführung kann auch derartig ge schehen, dass der in Tätigkeit gesetzte Zer stäuber feststeht und die horizontal angeord nete Druckwalze, sich um ihre Längsachse drehend, in horizontaler Richtung am Zer stäuber vorübergeführt wird.
Die beschriebenen Ausführungsbeispiele des Verfahrens ermöglichen es: 1. Dass man auf Druckwalzen jeder Ab messung und aus jedem Material Lösungen aller Art in entweder zusammenhängender oder durchbrochener, dünner oder dicker Schicht auftragen kann, um die Druckwalze dann auf alle photomechanischen Arten weiterbehandeln lind dadurch entweder eine Hoch-, Tief- oder I'lachdruckwalze herstellen zu können.
2. Dass man ein und dieselbe Druckwalze zum Teil mit einer zusammenhängenden, zum Teil mit einer durchbrochenen Schicht ganz gleichmäfo,ig überziehen kann.
3. Dass man auf ein und dieselbe Druck walze in entweder zusammenhängender oder durchbrochener, ganz gleichmässiger Schicht Substanzen in verschiedenen Lösungsmitteln über- und zwischeneinander auftragen kann.
Process for coating printing rollers with light-sensitive and other solutions. The invention aims to use the spraying method known per se for covering cylindrical bodies for pulling pressure rollers of any size and of any material, e.g. B. made of metal, rubber, glass, paper, with photosensitive or other solutions, z. B. with solutions of resins, albumin, glue, paints, in poorly or easily volatile oils or in liquids of a spirituous or watery nature.
This method enables the production of uniform, coherent or openwork layers, that is, layers with points and grains, which are easily suitable for photomechanical treatment.
The method is carried out, for example, as follows: The pressure roller to be provided with the layer of any kind is arranged horizontally in such a way that it can be rotated around its axis by hand or by machine. The solution intended for the layer is filled in an atomizer of any system.
The pressure roller is now set in rotation and the atomizer set in action either by hard or by machine at a shorter or greater distance in the horizontal direction along the pressure roller.
The design can also be done in such a way that the atomizer set in action is stationary and the horizontally arranged pressure roller, rotating around its longitudinal axis, is passed past the atomizer in the horizontal direction.
The described embodiments of the method make it possible: 1. That one can apply solutions of all kinds in either a coherent or open, thin or thick layer to printing rollers of any size and from any material, in order to then further treat the printing roller in all photomechanical ways, thereby either one To be able to produce letterpress, gravure or flat pressure rollers.
2. That one and the same pressure roller can be covered in part with a coherent layer, and in part with a perforated layer.
3. That you can apply substances in different solvents on top of and between each other on one and the same pressure roller in either a coherent or open, completely even layer.
