Description

Die Erfindung- bezieht sich auf das Wasser festmachen von Kreppapier auf beiden Seiten Verfahren zum Wasserfestmachen von Kreppapier sind zwar bekannt, haben aber den Nachteil, daß beim Durchziehen des Kreppapiers durch das flüssig· gehaltene Tränkungsmittel sich die Zwischenräume der Kreppfalten mit dem Paraffin 0. dgl. füllen, wodurch das Papier unansehnlich und brüchig· wird; beim Dehnen des " Kreppapiers bröckeln kleine Stückchen Paraffin ab und geben unimprägnierte Stellen frei, ganz abgesehen davon, daß der Paraffinverbrauch sehr groß ist. Beim direkten Auftragen des Paraffins mittels Walzen nehmen nur die erhöhten Stellen des Papiers Paraffin an, ohne den Stoff oder die Fasern ganz zu durchdringen, oder die Walzen drücken den von den Tränkungsmitteln etwa aufgeweichten Krepp flach.The invention relates to the water tightening of crepe paper on both sides Processes for waterproofing crepe paper are known, but have the disadvantage that when pulling through the Crepe paper through the liquid · held impregnating agent the interstices of the Fill crepe folds with paraffin 0, which makes the paper unsightly and brittle. will; When the crepe paper is stretched, small pieces of paraffin crumble off and release unimpregnated areas, quite apart from the fact that paraffin consumption is very big. When applying the paraffin directly by means of rollers, only the raised ones take Apply paraffin to the paper without completely penetrating the fabric or fibers, or the rollers flatten the crepe, which has been softened by the impregnating agents.

Es sind auch bereits Vorrichtungen zum einseitigen Imprägnieren von gewöhnlichem Papier mit wasserabstoßenden Stoffen bekanntgeworden, die aus einem geheizten Zylinder und einem den Zylindermantel teilweise umschließenden endlosen Tuch bestehen; zwischen beiden wird das zu imprägnierende Papier hindurchgeführt. Hierbei dient entweder das endlose Tuch oder der geheizte Zylinder als Auftragglied. Ferner hat man zum beidseitigen Auftragen von Flüssigkeit auf bahnförmiges Gut bereits Vorrichtungen benutzt, bei denen ein endloses Tuch und ein Zylinder die Auftragglieder bilden.There are already devices for one-sided impregnation of the ordinary Paper with water-repellent substances has become known, which consists of a heated cylinder and a cylinder jacket partially enclosing endless cloth; the paper to be impregnated is passed between the two. Here Either the endless cloth or the heated cylinder serves as the applicator. Further you already have to apply liquid to both sides of the web Devices used in which an endless cloth and a cylinder are the applicator members form.

Gemäß dem Verfahren nach der Erfindung zum Wasserfestmachen von Kreppapier auf beiden Seiten wird unter Benutzung ähnlicher Vorrichtungen das Kreppapier zwischen einem mit Auftragvorrichtung für Paraffin o. dgl. versehenen geheizten Zylinder und einem ebenfalls mit Imprägnierungsmittel-Auftragvorrichtung versehenen, um einen Teil des Zylindermantels ohne Druck herumgeführten endlosen Tuch hindurchgeführt. Hierdurch wird das Papier beidseitig ausreichend imprägniert, ohne daß die Krepp falten flach gedrückt werden und ohne daß sie durch zu starken Auftrag des Imprägnierungsmittels verklebt werden und dadurch ein brüchiges Erzeugnis ergeben könnten.According to the method of the invention for waterproofing crepe paper The crepe paper is sandwiched between both sides using similar devices a heated cylinder provided with an applicator for paraffin or the like and one also provided with impregnation agent application device to a Part of the cylinder jacket without pressure passed around endless cloth. As a result, the paper is sufficiently impregnated on both sides without the crepe wrinkling be pressed flat and without them by too strong application of the impregnation agent become glued and could result in a brittle product.

Eine' zur Ausführung des Verfahrens geeignete Vorrichtung, die als solche nicht Gegenstand des Schutzbegehrens ist, ist auf der Zeichnung dargestellt.A device suitable for carrying out the method, which as such is not The subject of the protection request is shown on the drawing.

In heizbaren Behältern i" und ib laufen Walzen 2" und 2*, die das Tränkungsmittel aufnehmen. Weitere Walzen 3° und 30 übertragen es auf einen heizbaren Zylinder 4 und auf das elastische, aus Gummi, Filz oder anderem weichen Stoff bestehende, um den Zylinder 4 laufende endlose Tuch 5. Die zu tränkende Kreppapierbahn 8 wird durch einen heizbaren Zylinder 7 vorgewärmt und läuft über die Leitwalze 9, worauf es von dem Tuch 5 mitgenommen und zwischen diesem und dem Zylinder 4 hindurchgeführt wird. Durch die Wärme des Zylinders 4 wird das Tränkungsmittel dünnflüssig, oder es verdampft und wird dann von dem Tuch 5 aufgefangen. Nun dringt das Tränkungsmittel in die Bahn 8 vollkommen ein. Die Regulierung der aufgetragenen Menge Paraffin oder Wachs erfolgt durch die Walzen 2 und 3.Rollers 2 "and 2 *, which take up the impregnating agent, run in heatable containers i" and i b. Further rollers 3 ° and 3 0 transfer it to a heatable cylinder 4 and to the elastic endless cloth 5 that runs around the cylinder 4 and consists of rubber, felt or other soft material. The crepe paper web 8 to be impregnated is preheated by a heatable cylinder 7 and runs over the guide roller 9, whereupon it is carried along by the cloth 5 and passed between this and the cylinder 4. Due to the warmth of the cylinder 4, the impregnating agent becomes thin or it evaporates and is then caught by the cloth 5. Now the impregnating agent penetrates completely into the web 8. The amount of paraffin or wax applied is regulated by rollers 2 and 3.
