Description

Verfahren zur Herstellung von Schallplatten und Schallbändern. Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Schallplatten und Schallbändern, dadurch gekennzeichnet, d@aß Bromsilber-(Halogensilber-)Emulsion als Kopierschicht zur Erzeugung eines Leimreliefs zur Anwendung kommt, um die Kopien -unmittelbar als Schallautomatsteuerorgane zu verwenden.Process for the production of records and sound tapes. object the invention is a process for the production of records and tapes, characterized in that d @ aß bromosilver (halosilver) emulsion as the copying layer to create a glue relief is used to make the copies -immediately to be used as automatic sound control organs.

Das .Verfahren ist rotationsphotographisch. Bildet die lichtempfindliche Bromsilberschicht auf .einem geeigneten Träger (Zellhorn, Zellulosetetraacetat, Kollo-dium,Gummi usw.) die Kopierschicht für ein photographisch gewonnenes Bild,der Schallwirkung, so entsteht die Furche im Leimgrund, und, zwar so, daß nach Entwicklung, Fixierung und Gerbung der Kopierschicht an den Bildstellen der Träger unter der Schallfurche frei von Überzug liegt.The process is rotational photography. Forms the photosensitive Bromide silver layer on a suitable carrier (cellular horn, cellulose tetraacetate, Collo-dium, rubber, etc.) the copy layer for a photographically obtained image, the Sound effect, this is how the furrow in the glue base is created, in such a way that after development, Fixing and tanning of the copy layer at the image areas of the carrier under the Sound groove is free of coating.

Die gehärtete Bildschicht dient zur Führung der Nadel :des Kontaktwerkzeuges, der Träger bildet die ebene Unterlage der Nadel.The hardened image layer is used to guide the needle: the contact tool, the carrier forms the level surface of the needle.

Gegenüber dem bisher Bekannten hat das Verfahren den Vorzug, daß Träger aus Stoffen von anderem Handelswert als Metalle benutzt wer'd'en können. Das dauernd zur Verfügung bleibende Schallbildnegativ wird, wie oben erwähnt, rotationsphotographisch auf mit hochlichtempfindlichenEmulsionen überzogene Träger, die rotationsphotographisch verwertbar sind und: derartige Emulsionen dauernd tragen können, aufkopiert.Compared to the previously known, the method has the advantage that the carrier can be used from materials of other commercial value than metals. That all the time The negative sound image that remains available is, as mentioned above, rotary photography on supports coated with highly light-sensitive emulsions which are rotationally photographic are usable and: can permanently carry such emulsions, copied.

PATENT-ANSPRUCII: Verfahren zur Herstellung von Schallplatten und Schallbändern, bei welchem das photographische Negativbild der Schallwirkung auf mit Bromsilber-(Halogensilber-) Emu ilsion überzogenen ,Stoff aufkopiert wird, dadurch gekennzeichnet, daß der aus rotationsphotographisch verwertbarem Stoff (z. B. Zellhorn, Gummi usw.) bestehende Träger der entwickelten, fixierten und an )den Bildstellen gehärteten Kopierschicht im Verlauf der Schallfurche, also an den löslich gebliebenen und entfernten, nicht belichteten Stellen, vom Überzug frei bleibt, so 4aß die gehärtete Leimschicht die Führung und der Träger .die Auflage des Schallabnahmewerkzeuges bildet.PATENT-ANSPRUCII: Process for the production of records and Sound bands, in which the photographic negative image of the sound effect on with bromosilver (halosilver) emulsion coated, fabric is copied on, thereby marked that the material that can be used for rotational photography (e.g. cell horn, Rubber etc.) existing carriers of the developed, fixed and at) the image areas hardened copy layer in the course of the sound groove, i.e. on the ones that remained soluble and removed, unexposed areas, remains free from the coating, so that the hardened Glue layer the guide and the carrier. The support of the sound absorption tool forms.
