Description

Verfahren zur Herstellung von Formstücken Die Erfindung betrifft ein Verfahren zum Herstellen von Formstücken aus pulverförmigen Stoffen durch kaltes oder warmes Pressen. Es ist bekannt, Formstücke, z. B. Knöpfe,' in der erwähnten Weise z. B. aus Hormnehl o. dgl. herzustellen.Method for the production of shaped pieces The invention relates to a Process for the production of shaped pieces from powdery substances by cold or hot pressing. It is known to use fittings, e.g. B. Buttons, 'in the mentioned Way z. B. from hormone meal o. The like. Manufacture.

Demgegenüber besteht die Erfindung darin, :daß das Pulver aus Elfenbein allein oder zugleich mit Schichten von Knochenmehl mit oder ohne Kunsthorn besteht. Wie Versuche ergeben haben, lassen sich aus diesen pulverförmigen Stoffen, was durchaus nicht vorauszusehen war, brauchbare Formstücke herstellen, nämlich solche, die hochglänzend aus der Form kommen, so daß sie keiner besonderen Nachpolitur bedürfen.In contrast, the invention consists in: that the powder is made of ivory alone or at the same time with layers of bone meal with or without artificial horn. As tests have shown, what can be done from these powdery substances could not be foreseen to produce usable fittings, namely those that are high-gloss come out of shape so that they do not require any special polishing.

Nach :dem erfindungsgemäßen Verfahren gelingt es, aus Elfenbeinmehl allein oder aus solchem zusammen mit den erwähnten anderen Abfallstoffen Scheiben, Ringe, Kugeln, Stäbe, Netzwerke, Artikel der Elektrotechnik und der Schreibmaschinenindustrie, Schmucksachen oder sonstige Preßlinge (Tabletten) herzustellen und dadurch Elfenbeinabfälle, Kunsthornabfälle u..dgl. bis zum letzten Rest aufzubrauchen. Dabei können auch außer dem fein gemahlenen Pulver gröbere Späne oder geformte feste Körper aus den genannten Stoffen in die Preßlinge eingebunden werden sowie auch Preßlinge bestimmter Farbe oder mehrfarbig hergestellt werden. Besonders wichtig ist die Erfindung insofern, als durch sie gelungen ist, Elfenbeinpulver, also einen Abfallstoff, den man bisher kaum zu benutzen verstand, zur Herstellung nützlicher wertvoller Gegenstände zu verwenden und, wenn man will, dabei zugleich die erwähnten Zusatzstoffe, insbesondere auch Kunsthornmehl, zu verwerten.According to the method according to the invention, it is possible to use ivory flour on their own or from such discs together with the other waste materials mentioned, Rings, spheres, rods, networks, items of electrical engineering and the typewriter industry, To produce jewelry or other compacts (tablets) and thereby ivory waste, Artificial horn waste and the like to use up to the last remainder. You can also except the finely ground powder coarser chips or shaped solid bodies from the named Substances are incorporated into the compacts as well as compacts of a certain color or multicolored. The invention is particularly important insofar as than it succeeded in creating ivory powder, a waste material that has hitherto been used hardly knew how to use, for the manufacture of useful valuable objects use and, if you want, at the same time the additives mentioned, in particular also artificial horn meal.
