KLASSE 55: Papierherstellung.CLASS 55: Paper manufacture.
Patentirt im Deutschen Reiche vom 14. März 1893 ab.Patented in the German Empire on March 14, 1893.
Durch das vorliegende Verfahren werden Papiere aus beliebigem Rohmaterial und in beliebiger Dicke während ihrer Herstellung auf der Papiermaschine so imprägnirt, dafs sich dieselben lederartig geschmeidig anfühlen und insbesondere die für Lederpressungen nothwendige Elasticität erhalten. Als Imprägnationsmittel eignen sich hierfür leicht lösliche OeIe, wie Glycerin etc., oder nicht trocknende, in Alkohol lösliche OeIe, wie Ricinusöl, Rhodonöl, Icocaöl, Celesteröl, Rofskastanienöl u. s. w.The present process produces papers from any raw material and in of any thickness so impregnated during their manufacture on the paper machine that they feel leather-like, supple and especially those necessary for pressing leather Maintain elasticity. Easily soluble oils are suitable as impregnation agents for this purpose, such as glycerine etc., or non-drying, alcohol-soluble oils such as castor oil, rhodon oil, Icoca oil, celester oil, rofs chestnut oil and so on.
Das Papier wird auf der Papiermaschine, .und zwar am zweckmäfsigsten vor dem Passiren der letzten Nafspresse durch einen Behälter geführt, der eine Mischung von Glycerin oder einem leicht löslichen OeI mit Wasser oder einem Gemenge von solchen Stoffen gefüllt ist. Es können auch Mischungen von in Alkohol löslichen, nicht trocknenden Oelen Verwendung finden, doch werden im allgemeinen die erstgenannten Mischungen der Billigkeit halber in Betracht kommen. Anstatt das Papier durch einen mit Glycerin etc. gefüllten Behälter zu führen, kann dasselbe auch durch Anspritzen mit den vorbenannten Stoffen oder in sonst geeigneter Weise imprägnirt werden.The paper is made on the paper machine, and most appropriately before it is passed the last Nafspresse passed through a container containing a mixture of glycerine or an easily soluble oil filled with water or a mixture of such substances is. Mixtures of alcohol-soluble, non-drying oils can also be used Find use, but are generally the first-mentioned mixtures of To be considered for the sake of equity. Instead of the paper by one filled with glycerine etc. Carrying out containers can also do the same by spraying the aforementioned substances or impregnated in some other suitable manner.
Am besten hat sich hierzu ein Gemenge von Glycerin und Wasser von ca. 70B. bewährt. A mixture of glycerine and water of approx. 7 ° C. has proven to be best for this purpose.
Die beim Passiren des Papieres durch die Nafspresse ausgepreiste Flüssigkeit wird in einem Behälter wieder gesammelt und zum Verdünnen des bei der Imprägnirungsflüssigkeit verwendeten Oeles verwendet, wodurch ein Verlust an letzterem vermieden wird.The liquid that is priced out when the paper is passed through the press is in collected again in a container and used to dilute the impregnation liquid used oils, whereby a loss of the latter is avoided.
Das in einer der vorbeschriebenen Arten präparirte Papier kann nun direct geprefst werden, oder es kann demselben noch vor dem Pressen ein beliebiger Farbanstrich gegeben werden.The paper prepared in one of the ways described above can now be pressed directly or it can be given any coat of paint before pressing will.
