Verfahren zur Imprägnierung von Rollenkopierp apier.
Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren zur Imprägnierung von Rollenkopierpapier, welches bezweckt, eine Anstrocknl1ng desselben im vorgefe'chteten Z ; stande an der Stirnseite zu vermeiden und gleichzeitig das Papier derart zu versteifen, dass mit der Dicke des Papieres weit unter das bisher bekannte Mass gegangen werden kann.
Diese angestrebte Wirk ng wird dadurch erreicht, dass das Papier an den Rändern mit stark verdünnten Lösungen Wasser abstossender Stoffe getränkt wird. Es kommt beispielsweise eine Lösung von etwa 3-6% Paraffin in Tetrachlorkohlenstoff in Betracht.
EMI1.1
Maschinen Überhaupt nicht verwendbar ist, weil die Walzen verkleben, wodurch ein Reissen des Papieres, respektive Störungen (Hängenbleiben der freien Papierbahn, dadurch schiefes Schneiden etc.) bedingt werden. Die Ränder werden brüchig, schaben und sciuppen sieh ab. Eine Imprägnierung mit schmelzflüssigen bzw. erwärmten Imprägniernngsbädern bedingt weiters die Gefahr, dass bei zu hoher Erhitzung die Festigkeit des Papieres Schaden leidet.
Öle und Fette sind für die Imprägnierung des Randes von Kopierpapier für den angegebenen Zweck gleichfalls nicht geeignet, weil hiedurch ein Erweichen der Papierfasern und damit ein leichtes Zerreissen, also ein gebrauchshinderndes Ergebnis bei einem noch stärkeren Papierstoff bedingt ist.
EMI1.2
Imprägnierungsmasse nur so viel hievon auf das Papier gebracht wird, um die Austrocknung zu verhindern, ohne brüchig zu werden.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

Process for the impregnation of roll copier paper.
The subject matter of the present invention is a process for the impregnation of roll copier paper, the purpose of which is to dry it out in the pre-tempered Z; was to be avoided on the front side and at the same time to stiffen the paper in such a way that the thickness of the paper can go well below the previously known level.
This desired effect is achieved by soaking the paper at the edges with highly diluted solutions of water-repellent substances. For example, a solution of about 3-6% paraffin in carbon tetrachloride can be used.
EMI1.1
Machines cannot be used at all because the rollers stick together, causing the paper to tear or malfunctions (free paper web sticking, resulting in crooked cutting, etc.). The edges become brittle, scrape and sciop off. Impregnation with molten or heated impregnation baths also creates the risk that the strength of the paper will suffer if the temperature is too high.
Oils and fats are also unsuitable for impregnating the edge of copier paper for the stated purpose, because they soften the paper fibers and thus tear them easily, which is a use-hindering result with an even thicker paper stock.
EMI1.2
Impregnation compound is only applied to the paper as much as possible to prevent it from drying out without becoming brittle.
