Description

Verfahren zur Herstellung von Schallplatten oder -walzen. Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Schallplatten oder -walzen auf photomechanischem Wege.Process for the production of records or cylinders. object The invention relates to a method of making records or cylinders photomechanical way.

Dem Bekannten gegenüber weist das Verfahren gemäß der Erfindung wesentliche Unterschiede sauf, die ,darin gipfeln, daß als Träger der lichtempfindlichen Schicht ausschließlich nichtmetallische, organische Stoffe der genannten .Art verwendet werden, die unter der Einwirkung des Ätz- bzw. Lösemittels keine rauhe und körnige Beschaffenheit annehmen, wie es bei Metallen erfahrungsgemäß der Fall ist. Die unter dem Lösemittel ins Fließen geratende Materie bildet nämlich im Erstarren ganz glatte Flächen, so daß das Schall@abnahmewerkzeug sein geeignetes Auflager vorfindet.In relation to what is known, the method according to the invention has essential features Differences that culminate in the fact that the photosensitive layer is supported only non-metallic, organic substances of the type mentioned are used that are not rough and grainy under the action of the etchant or solvent Assume quality, as experience has shown to be the case with metals. The under Matter that comes into flow with the solvent forms quite smooth when it solidifies Surfaces so that the Schall @ acceptance tool finds its suitable support.

Auch lassen sich auf nichtmetallischen ,Stoffen alle hoch lichtempfindlichen, rotationsphotographisch verwertbaren Emulsionen ahne Zwischenverfahren leicht lagern und aufbewahren, iso daß der Bromsilberprozeß mit allen seinen Vorzügen zur Anwendung gelangen kann.All highly light-sensitive, Easily store rotationally usable emulsions without intermediate processes and keep it, iso that the bromosilver process with all its advantages can be used can get.

Der in der photographischen Kammer gewonnene Film der Klangwirkung :bildet die Grundlage der Reliefätzung photomechanisch verwertbarer Stoffe. Das photomechanisch erzeugte Relief ist die Steuerplatte des Schal!-automaten.The film of the sound effect obtained in the photographic chamber : forms the basis of the relief etching of photomechanically usable materials. That The photo-mechanically generated relief is the control plate of the automatic formwork machine.

Das photomechanische Verfahren gipfelt darin, einen ätzbaren bz-w. lösbaren, nicht metallischen Stoff (Zellhorn, Kollodium, Gummi, Kautschuk o. dgl.) mit einer Bromsilbergelatine zu überziehen, die bildgemäß belichtet wird. Die gehärtete Gelatineschicht bildet eine sogenannte Ätzschablone, unter deren Schutz der Schichtträger angeätzt ibzw. gelöst wird, so daß darauf photomechanisch ein Reliefnachbild entsteht.The photomechanical process culminates in an etchable or w. detachable, non-metallic material (cell horn, collodion, rubber, caoutchouc etc.) to be coated with a silver bromide gelatin, which is exposed imagewise. The hardened one Gelatin layer forms a so-called etching stencil, under which the layer substrate is protected etched ibzw. is released, so that a relief afterimage is created on it photomechanically.

Das vorliegende Verfahren wird zunächst rotationsphotographisch in bekannter Weise gehandhabt, dann photomechanisch. Nach Belichtung, Entwicklung, Fixierung und Härtung des photographischen Bildes erfolgt gemäß der Erfindung unter dem Schutze der ätzfesten Bildschidht die Ätzung bzw. Lösung des Schichtträgers auf photomechanischem Wege, so daß im Schichtträger die Klangfurche entsteht.The present process is first carried out using rotary photography handled in a known manner, then photomechanically. After exposure, development, Fixing and hardening of the photographic image takes place according to the invention under the protection of the etch-proof image is the etching or dissolution of the substrate by photomechanical means, so that the sound groove is created in the layer support.
