Description
Verfahren zum Vervielfältigen reliefartiger Gebilde, insbesondere von Schriftsätzen in Blindenschrift Für die Vervielfältigung reliefartiger Gebilde auf spezifisch leichtem, biegsamem Material, wie es beispielsweise bei Herstellung von Schriftsätzen in Blindenschrift erforderlich ist, war man darauf angewiesen, von dem Original zunächst ein Negativ auf galvanischem Wege herzustellen, das dann als Matrize zur Prägung der Reproduktionen in Papier, Pappkarton o. dgl. diente. Dieses Verfahren erforderte eine verhältnismäßig große und kostspielige Apparatur, war also nur dann anwendbar, wenn eine regelrechte Fabrikation betrieben werden sollte.Process for duplicating relief-like structures, in particular of briefs in Braille For the reproduction of relief-like structures on specifically light, flexible material, as is the case, for example, in manufacture of written submissions in Braille is required, one had to rely on to first produce a negative from the original by galvanic means, which then Served as a die for embossing the reproductions in paper, cardboard or the like. This process required a relatively large and expensive apparatus, was therefore only applicable if a regular production was carried out should.
Lm nun zu ermöglichen, daß auch in kleiner Auflage und unabhängig von einem maschinellen Betrieb derartige Abzüge von einem Original auf reliefartiger Basis gemacht werden können, wird vorgeschlagen, wie folgt zu verfahren: Auf das Original, das aus einem in Wasser nicht löslichen oder quellbaren Körper bestehen muß, wird in bekannter Weise eine Schicht von Gelatine oder einem ähnlichen Produkt in wäßriger Dispersion aufgetragen. Zur Erhöhung der Elastizität kann man je nach Bedarf Zusätze von Glycerin oder einem anderen geeigneten Plastifizierungsmittel machen. Nach dem Trocknen wird die Schicht, die nunmehr alle Einzelheiten der Oberfläche des Grundkörpers zeigt, von demselben abgezogen und gegebenenfalls durch Aufkleben auf eine Unterlage mechanisch verfestigt.Lm now enable that even in small editions and independently Such prints made by a machine shop from an original to a relief-like one Can be made, it is suggested to proceed as follows: On the Original consisting of a body that is insoluble or swellable in water must, in a known manner, a layer of gelatin or a similar product applied in aqueous dispersion. To increase the elasticity one can depending on Requires additions of glycerine or another suitable plasticizer do. After drying, the layer is now all the details of the surface of the base body shows, removed from the same and, if necessary, by gluing mechanically solidified on a base.
Auf die gleiche Weise wird jetzt von diesem so erhaltenen Negativ ein Abdruck hergestellt, indem man dafür Lösungen von Celluloseestern, -äthern o. dgl. in einem geeigneten Lösungsmittel verwendet, das die Gelatine nicht angreift. Auch dieser Lösung können geeignete Mengen von Harzen, Weichmachungsmitteln oder Füllstoffen zur Veränderung der mechanischen Eigenschaften bzw. zur Verbilligung zugesetzt werden.The negative obtained in this way is now made in the same way an impression is made by using solutions of cellulose esters, ethers, etc. Like. Used in a suitable solvent that does not attack the gelatin. Also this solution can contain suitable amounts of resins, plasticizers or Fillers to change the mechanical properties or to make them cheaper can be added.
Die so erhaltenen Kopien der Originalvortagen lassen sich in verhältnismäßig dünnwandiger Beschaffenheit herstellen, wodurch es ermöglicht wird, eine größere Anzahl von ihnen auf beschränktem Raum unterzubringen, sie in Buchform zu binden usw.The copies of the original presentations obtained in this way can be in proportion produce a thin-walled texture, which makes it possible to produce a larger To accommodate a number of them in a limited space, to bind them in book form etc.
