Description
Löschpapier oder Löschkarton. Patentiert im Deutschen Reiche vom 24. März 1911 ab.Blotting paper or blotting cardboard. Patented in the German Empire on March 24, 1911 .
Die Erfindung hat den Zweck, die Ränder von Löschpapieren oder Löschkartons widerstandsfähiger zu machen und so das Zerreißen derselben zu verhindern. Um dies zu erreichen, werden die Ränder mit in Wasser unlöslichen oder schwerlöslichen Stoffen imprägniert. Diese besondere Eigenschaft kann letzteren auch durch geeignete chemische Behandlung verliehen werden.The purpose of the invention is to make the edges of blotting papers or blotting boxes more resistant to make and thus to prevent the tearing of the same. To do this, the edges are made with water-insoluble or poorly soluble substances. The latter can also achieve this special property through suitable chemical treatment be awarded.
ίο Die ungeleimten Löschpapiere oder Löschkartons haben den schwerwiegenden Übelstand, daß sie Zerreiß Wirkungen kaum widerstehen. Dieser Übelständ, der schon bei trockenen Blättern stark auftritt, wird noch empfmdricher, wenn die Blätter naß sind, z. B, bei Benutzung derselben zum Kopieren von Briefen.ίο The unsized blotting paper or blotting boxes have the serious problem, that they hardly withstand tearing effects. This evil, which is already dry Leaves occurs strongly, is even more susceptible when the leaves are wet, e.g. B, at Use the same for copying letters.
; Man hat versucht, diesem Übelstand dadurch abzuhelfen, daß zur Herstellung der Löschpapiere oder Löschkartons Rohstoffe von hohem Widerstand verwendet wurden, was jedoch eine erhebliche Preiserhöhung im Gefolge hatte.; Attempts have been made to remedy this deficiency by producing the Blotting papers or blotting boxes raw materials of high resistance were used what however, it had a significant price increase in the wake.
Da die Blätter fast immer zunächst an den Rändern zerreißen, so kann man das Zerreißen der Blätter durch Erhöhung der Festigkeit der Ränder fast vollständig beseitigen. Zu diesem Zwecke genügt es, wenn dieselben auf einer geringen Breite mit in Wasser unlöslichen oder schwerlöslichen Produkten imprägniert werden, z. B. mit Firnissen, mit Fett-Substanzen, mit Lösungen von Harzseifen, mit Leim oder Gelatine, mit Kasein, mit pflanzlichen Klebstoffen usw., welche eventuell durch adstringierende Körper oder Präzipitate, wie z. B. Tannin, Alaun, Formol usw., behandelt worden sind.Since the sheets almost always tear at the edges first, you can tear the sheets Almost completely eliminate the leaves by increasing the strength of the edges. to For this purpose it is sufficient if they are insoluble in water over a small area or poorly soluble products are impregnated, e.g. B. with varnishes, with fatty substances, with solutions of resin soaps, with glue or gelatine, with casein, with vegetable adhesives, etc., which possibly by astringent bodies or precipitates, such as. B. tannin, alum, formula, etc. treated have been.
Die in dieser Weise imprägnierten und getrockneten Ränder besitzen eine große Widerstandsfähigkeit gegen Zerreißen und behalten selbst bei Gegenwart von Wasser ihre ursprüngliche Festigkeit bei.The edges impregnated and dried in this way are extremely resistant against tearing and retain their original properties even in the presence of water Strength at.
