Description

Verfahren zum Zusammenkleben von Folien aus Celluloseestern mit Papier, Karton u. dgl. Das vorliegende Verfahren betrifft das Zusammenkleben von Folien aus Celluloseestern mit Papier, Karton u. dgl. unter Verwendung von Leim, Gelatine und ähnlichen Bindemitteln.Process for gluing together foils made of cellulose esters with paper, Cardboard and the like The present method relates to gluing sheets together made of cellulose esters with paper, cardboard and the like using glue, gelatin and similar binders.

Es ist von der Kartonagenindustrie her bekannt, mit Leim überzogene Papierklebestreifen zu verwenden, welche durch Anfeuchten zum Kleben gebracht werden. Dieses Verfahren hat den Nachteil, daß durch den `Vassergehalt des Klebmittels, der von dem Papier aufgenommen wird, Verdehnungen des Papiers, der Pappe usw. entstehen und beim Trocknen, Blasen und Falten gebildet werden. Anderseits ist es bekannt, Blattmetall auf Papierflächen mit Hilfe von Klebstoffen, insbesondere Harzen, zu befestigen, welche nicht durch Befeuchten, sondern durch Erwärmen zum Kleben gebracht werden.It is known from the cardboard industry, coated with glue To use paper adhesive strips, which are made to stick by moistening. This method has the disadvantage that due to the `water content of the adhesive, which is absorbed by the paper, stretching of the paper, cardboard, etc. arise and when drying, bubbles and wrinkles are formed. On the other hand, it is known Sheet metal on paper surfaces with the help of adhesives, in particular resins fasten, which are not made to stick by moistening, but by heating will.

Es wurde nun gefunden, daß man Folien von Celluloseestern mit Papier, Karton u. dgl. zweckmäßig in der Weise vereinigt, daß man die Folie mit einer stark verdünnten Klebstofschicht aus Leim, Gelatine oder ähnlichen Bindemitteln versieht, welche vor dem Aufkleben oberflächlich befeuchtet und mit Hilfe einer heißen Walze erwärmt wird. Durch die beschriebene Vereinigung der beiden an sieh bekannten Klebeverfahren erreicht man, daß die nur oberflächlich aasgequollene Klebstoffschicht unter der "#Virkung der Wärme der Walze schmilzt und das Papier innig mit dem Celluloseester verbindet, ohne daß Verdehnungen oder Faltenbildungen entstehen. Bei dem Aufbringen der Klebstoffschicht auf die Celluloseesterfolien zeigt sich der Nachteil, daß der Klebstoff sich nicht fest genug mit der Zellhornoberfläche verbindet. Diese Schwierigkeit wird erfindungsgemäß dadurch überwunden, daß das Zellhornblatt vor dem Aufbringen der Klebstofischicht mit einer geeignet-en Präparatian versehen wird. Hierzu eignen sich insbesondere dünne Chromatgela.tinelösungen, wie sie in der photographischen Industrie für die Vorbereitung des als Schichtträger dienenden Films für den Emulsionsauftrag verwendet werden.It has now been found that sheets of cellulose esters with paper, Cardboard and the like are suitably combined in such a way that the film is wrapped with a strong provides a diluted adhesive layer made of glue, gelatine or similar binders, which is moistened on the surface before sticking and with the help of a hot roller is heated. By combining the two known adhesive processes described above one achieves that the only superficially swollen adhesive layer under the "# Effect of the heat of the roller melts and the paper becomes intimate with the cellulose ester connects without stretching or wrinkling. When applying the adhesive layer on the cellulose ester films has the disadvantage that the Adhesive does not bond firmly enough to the cell horn surface. This difficulty is overcome according to the invention that the cell horn sheet before application the adhesive layer is provided with a suitable preparation. Suitable for this In particular, thin chromate gel.tinelösungen, as they are in the photographic Industry for the preparation of the film serving as the substrate for the application of the emulsion be used.

PATENTANSPRUCH: Verfahren zum -Zusammenkleben von Folien- aus Celluloseestern mit Papier. Karton u. dgl. unter Verwendung von Leim, Gelatine oder ähnlichen Bindemitteln, dadurch gekennzeichnet, daß die Folie mit einer an sich bekannten Präparation. wie z. B. aus Chromatgelatine, und darauf mit einer gleichmäßigen dünnen Klebstoffschicht überzogen und getrocknet wird. um bei der Verwendung--nach oberflächlicher Anfeuchtung auf einer heißen Fläche mit dem Papier, Karton o. dgl. zusammengeführt zu «-erden, so daß durch Schmelzen der gequollenen hlebstoffschicht die Vereinigung der Folie mit dem Papier bewirkt wird. PATENT CLAIM: Process for gluing together foils made of cellulose esters with paper. Cardboard and the like using glue, gelatin or similar binders, characterized in that the film is made with a preparation known per se. such as B. from chromate gelatin, and then coated with an even thin layer of adhesive and dried. in order to be brought together with the paper, cardboard or the like after superficial moistening on a hot surface, so that the fusion of the swollen adhesive layer brings about the union of the film with the paper.
