Verfahren zur Herstellung eines Radiermittels.
Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren zur Herstellung eines Hadiermittels, Starke Lösungen indifferenter Salze, insbesondere Chlormagnesiumlauge, Chlorkalziumlauge, Chlorzinklauge, geben bekanntlich beim Vermischen mit Stärkemehl oder stärkereichem Mehl und Erwärmung der Mischung eine teigartige Masse, die zu einzelnen Verwendungszwecken als Ersatz für Gummimischungen vorgeschlagen ist. Von solchen Mischungen wird für das Verfahren der Erfindung Gebrauch gemacht. Beispielsweise wird einer etwa 3000 Chlormagnesium enthaltenden Lauge genügend Kartoffelstärke in der Kälte zugemischt und das Gemisch zu einem Teige angewirkt.
Diesem Teige wird besonders zur Herstellung von Bleistift-Radiermitteln noch Holzschliff hinzugeführt, so dass ein ziemlich fester Teig entsteht. Um die Schabefähigkeit für Tinteradierung zu erhöhen, können, wie bei der Herstellung von Radiergummi aus Gummimasse bekannt, auch Zusätze harter mineralischer Stoffe in Pulverform gemacht werden, z. B. von fein gemahlenem Glas, fein gemahlenem Sand und ähnlichen sonst zum Schleifen dienenden mineralischen Pulvern.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Process for making an eraser.
The subject of the present invention is a process for the production of a whipping agent, strong solutions of indifferent salts, in particular chloromagnesium liquor, chlorine calcium liquor, chlorzinc liquor, are known to give a dough-like mass when mixed with starch flour or starch-rich flour and the mixture is heated, which can be used for individual purposes as a substitute for rubber mixtures is suggested. Use is made of such mixtures for the method of the invention. For example, enough potato starch is mixed into a lye containing about 3000 chlorine magnesium in the cold and the mixture is worked into a dough.
Wood pulp is added to this dough, especially for the production of pencil erasers, so that a fairly firm dough is created. In order to increase the scraping ability for tint erasing, additions of hard mineral substances in powder form can be made, as is known in the production of erasers from rubber compound, e.g. B. of finely ground glass, finely ground sand and similar mineral powders otherwise used for grinding.
