Description

Verfahren zum Kaschieren von Viskosefolien mit Metallfalien mittels wäßriger Klebstofflösungen Gegenstand der vorliegenden Erfindung ist ein Verfahren zum Kaschieren einer.Vislcosefolie mit einer Metallfolie.Process for lamination of viscose films with metal filings by means of Aqueous Adhesive Solutions The present invention relates to a method for lamination of a viscose film with a metal foil.

Das Kaschieren von Viskosefolien mit Metallfolien mittels wäßriger Klebstofflösungen ist an sich bekannt. Die auf die Viskosefolien aufgetragene wäßrige Klebstofflösung durchnäßt die Vislcosefolien. Nach der Vereinigung der mit Klebstoff bestrichenen Fol:cn mit den Metallfolien auf Trockentrommeln schrumpft die Viskosefolie und zieht sich beim Trocknen zusammen. Dieser.Nachteil wird durch das Verfahren gemäß .der Erfindung behoben, und zwar dadurch, daß die zweckmäßig in an sich bekannter Weise vorher angerauhten Viskosefolien zunächst einseitig mit einer hauchdünnen Schicht eines beliebigen, nicht trocknenden Öls überzogen «erden. Erst dann wird durch Auftragwalzen einseitig eine mit wäßriger Klebstofflösung überzogene Metallfolie auf der nicht mit dem Ölüberzug versehenen Seite der Viskosefolie aufgelegt, beide Folien zwischen Walzen durchgeführt und auf geheizten Trockenwalzen getrocknet. Abschließend kann auf die mit der Metallfolie kaschierte Viskosefolie noch in an sich bekannter Weise eine Nitrocelluloselac9;schiclit durch eine Lackauftragswalze aufgebracht und getrocknet werden.The lamination of viscose films with metal foils by means of aqueous Adhesive solutions are known per se. The aqueous applied to the viscose Adhesive solution soaks the viscose films. After uniting the with glue If fol: cn coated with the metal foils on drying drums, the viscose foil shrinks and contracts as it dries. This disadvantage is caused by the process solved according to .the invention, in that the expedient in per se known Apply previously roughened viscose film on one side with a very thin one Coated with a layer of any non-drying oil. Only then will A metal foil coated with an aqueous adhesive solution on one side by application rollers placed on the side of the viscose film not provided with the oil coating, both Films passed between rollers and dried on heated drying rollers. Finally, the viscose film laminated with the metal foil can also be applied to As is known, a nitrocellulose lac9; slides through a lacquer application roller applied and dried.

Zur Durchführung des Verfahrens gemäß der Erfindung können alle Klebstoffe verwendet «erden, welche in Wässer löslich sind.All adhesives can be used to carry out the method according to the invention used «earths which are soluble in water.

Die Viskos.efolie kann man nach dem Kaschieren, falls erforderlich, mit einem Nitrocelluloselack in an sich bekannter «'eise ausrüsten.After lamination, the viscose film can, if necessary, Equip with a nitrocellulose lacquer in a known manner.

PATENTANSPRUCH: Verfahren zum Kaschieren einer Niskosefolie mit einer Metallfolie mittels wäßriger Klebstofflösungen, dadurch gekennzeichnet, daß auf die zweckmäßig in an sich bekannter Weise vorher angerauhte Viskosefolie zunächst einseitig eine hauchdünne Schicht eines beliebigen. nicht trocknenden Öls aufgebracht, eine einseitig durch Auftragwalzen mit einer Nväßrigen Klebs.tofflösung überzogene Metallfolie auf die Viskosefolie auf der nicht mit dem Ölüberzug versehenen Sexte der Viskosefolie aufgelegt, beide Folien zwischen Walzen durchgeführt und auf geheizten Trockenwalzen getrocknet werden. Zur Abgrenzung des Anmeldungsgegenstandes vom Stand der Technik sind im Erteilungsverfahren folgende Druckschriften in Betracht gezogen worden: deutsche Patentschriften ... Nr.571958, 589 589, 532 628, 6o4 olo, 669 652; schweizerische Patentschriften \7r. i38000, 131 112; britische Patentschrift ..... - 313 550; Kunststoffe, (193o), S.138; Halama, Transparentfolien, (1932), S. 174;'5. PATENT CLAIM: A method for laminating a niskose film with a metal film by means of aqueous adhesive solutions, characterized in that on one side of the viscose film, which is expediently previously roughened in a manner known per se, an extremely thin layer of any. non-drying oil is applied, a metal foil coated on one side by application rollers with an aqueous adhesive solution is placed on the viscose foil on the sixth of the viscose foil not provided with the oil coating, both foils are passed between rollers and dried on heated drying rollers. To distinguish the subject matter of the application from the state of the art, the following publications were considered in the granting procedure: German patents ... Nos. 571958, 589 589, 532 628, 6o4 olo, 669 652; Swiss patents \ 7r. i38000, 131 112; British Patent ..... - 313 550; Kunststoffe, (193o), p.138; Halama, Transparencies, (1932), p. 174; '5.
