Druck oder mit Hilfe eines Klebemittels mit der pastenförmigen oder plattenförmigen Unterlage verbunden werden oder die letztere kann mit Lösungen von Azetylzellulose durch Eintauchen, Aufstreichen, Aufspritzen oder in einer sonstwie passend erscheinenden Weise überzogen werden.
Dieser Vorgang kann mehrmals, und zwar entweder mit der gleichen Lösung oder mit Lösungen verschiedener Zusammensetzung wiederholt werden und können hiedurch Azetatschichten von verschiedenen Eigenschaften und von verschiedenen Härtegraden übereinander gelagert werden, so dass beispielweise auf einem Kerne von sprödem Harz zunächst eine weiche, sehr zähe Azetatschicht aufgebracht wird, um die Sprödigkeit der Harzplatte aufzuheben und hierüber ein dünner, harter Azetatüberzug, um die Widerstandsfähigkeit der Schrift gegen Abnutzung durch den Stahlstift zu erhöhen.
A ! s Lösungsmittel kommen hauptsächlich solche Lösungsmittel der Azetylzellulose in Betracht, welche die Kernmasso möglichst wenig aufweichen, wie beispielsweise bei Schellackplatten Mischungen von Alkohol und Benzol, doch kann die Kern masse auch durch eine entsprechende Zwischenschicht, wie beispielsweise eine dünne Gelatineschicht oder Papierauflage, vor der Einwirkung der Lösungsmittel geschützt werden. Es lassen sich auch Azetatlösungen in Lösungsmitteln, welche die Kernschicht stark angreifen. anwenden, wenn man diese Lösungen in hochkonzentrierter oder hochviskoser, am besten

ein in der Kälte sofort erstarrender Überzug bildet.
Man kann naturgemäss auch die Lösungen auf geeigneten Unterlagen vorher ein-

aus dünner Metallfolie, mit der Kernschicht vereinigen, insbesondere dann, wenn man die letztere nicht schon vorher bildet sondern pastenförmig zwischen die Azetatschichten einbettet und in der Pressform selbst zwischen der unteren und oberen Azetatschicht gleichmässig verteilt. Man kann auch die plastische Kernschicht vollkommen ausschalten und die Schallplatten durch doppelseitigen Azetylzelluloseüberzug auf streifenförmig hergestellten Materialien, z. B. auf Papier-oder Kartonstreifen, herstellen, so dass die Schallplatten einfach durch Prägung und Ausstanzen aus diesen Streifen hergestellt werden können.
PATENT-A PR ÜCHE :
1. Verfahren zur Herstellung prägefähiger Sprechmaschinenplatten. dadurch gekennzeichnet, dass man ein geeignetes plattenförmiges oder durch Pressung in Platten form zu bringendes Material vor. während oder nach der Prägung mit einer Schicht von Azetylzellulose oder mit einer Schicht einer Mischung von Azotylzellulose mit den Zelluloseester in der Wärme plastisch machenden Stoffen (Kampferersatziuittein) mit oder ohne Zusatz von organischen oder anorganischen Füllmaterialien überkleidet.

Pressure or with the aid of an adhesive can be connected to the paste-like or plate-like base or the latter can be coated with solutions of acetyl cellulose by dipping, brushing, spraying or in any other way that appears suitable.
This process can be repeated several times, either with the same solution or with solutions of different compositions, and acetate layers of different properties and degrees of hardness can thus be stacked on top of one another, so that, for example, on a core of brittle resin, initially a soft, very tough acetate layer is applied to relieve the brittleness of the resin plate and over it a thin, hard acetate coating to increase the resistance of the writing against wear by the steel pen.
A! Solvents are mainly those solvents of acetyl cellulose that soften the core mass as little as possible, such as mixtures of alcohol and benzene in shellac records, but the core mass can also be preceded by an appropriate intermediate layer, such as a thin gelatin layer or paper overlay the solvents are protected. Acetate solutions can also be used in solvents, which strongly attack the core layer. Apply when you get these solutions in highly concentrated or highly viscous, best
EMI2.1
forms a coating that solidifies immediately in the cold.
You can of course also provide the solutions beforehand on suitable documents.
EMI2.2
made of thin metal foil, unite with the core layer, especially if the latter is not formed beforehand but embedded in paste form between the acetate layers and evenly distributed in the mold itself between the lower and upper acetate layers. You can also switch off the plastic core layer completely and replace the records with a double-sided acetyl cellulose coating on materials produced in strips, e.g. B. on paper or cardboard strips, so that the records can be easily made by embossing and punching from these strips.
PATENT CHECKS:
1. Process for the production of embossable speaking machine plates. characterized in that a suitable plate-shaped material or material which is to be brought into shape by pressing in plates is provided. during or after the embossing with a layer of acetyl cellulose or with a layer of a mixture of azotyl cellulose with the cellulose ester in the heat plasticizing substances (camphor substitute) with or without the addition of organic or inorganic fillers.
