Description

Verfahren, um Leder für Walzen für Druckereimaschinen und ähnliche Maschinen undurchdringlich für Farben usw. zu machen. Bei Steindruck werden hauptsächlich Lederwalzen verwendet, um die Farbe auf die Druckfläche aufzutragen. Um zu verhindern, daß die Farbe in das Leder eindringt, werden bisher die Walzen vor ihrer Benutzung mit Firnis getränkt. Diese Behandlung kann jedoch nicht verhindern, daß die Farbe in das Leder eindringt, wodurch bei der Reinigung der Walzen große Schwierigkeiten entstehen. Man muß die Walzen mehrmals reinigen und mit geeignetenWerkzeugen, wie Messern usw. durch Schaben die Farbe zu entfernen suchen.Process to make leather for rollers for printing machines and the like To make machines impenetrable to colors etc. In the case of lithography, mainly Leather rollers are used to apply the ink to the printing surface. To prevent, that the color penetrates into the leather, the rollers are so far before they are used soaked with varnish. However, this treatment cannot prevent the color penetrates the leather, which makes cleaning the rollers very difficult develop. You have to clean the rollers several times and use suitable tools, such as Knives, etc., try to remove the paint by scraping.

Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Behandeln von Lederwalzen für Steindruck und auf nach diesem Verfahren behandelte Walzen, und sie beruht darauf, durch eine geeignete Behandlung das Eindringen der Farbe in das Leder zu verhindern, so daß durch einfaches Abwaschen mit geeigneten Waschmitteln die Walzen gereinigt werden können. Das Wesen der Erfindung besteht darin, daß das Leder mit im Leder gebildetem Faktis nach folgendem Verfahren versehen wird.The present invention relates to a method of treatment of leather rollers for lithography and rollers treated with this method, and it relies on the penetration of the color by a suitable treatment to prevent in the leather, so that by simply washing it off with suitable detergents the rollers can be cleaned. The essence of the invention is that the Leather is provided with factice formed in the leather according to the following process.

Man mischt gekochtes Leinöl mit io bis i2Prozent in Benzin oder Benzol verdünntem Chlorschwefel und läßt das Leder diese Mischung bis zur Sättigung einziehen. Nach kurzer Zeit ist die Faktisbildung vollzogen. Die bei der Faktisbildung entstandene Salzsäure wird durch Abwaschen mit Sodalösung neutralisiert. Dieses Faktis ist praktisch unlöslich in allen organischen Lösungsmitteln und gibt dem Leder eine größere Elastizität als vorher, was nur von Vorteil ist.Mix boiled linseed oil with 10 to 12 percent in gasoline or benzene diluted chlorosulfur and lets the leather absorb this mixture until it is saturated. After a short time, the factoring is complete. The one created during the formation of the factis Hydrochloric acid is neutralized by washing it off with a soda solution. This fact is practical insoluble in all organic solvents and gives the leather greater elasticity than before, which is only beneficial.

Weil das Verfahren ein vollständiges Durchdringen des Leders mit Faktis zuläßt, ist eine Entfernung des Faktis vom Leder nicht möglich.Because the process completely penetrates the leather with factice allows, a removal of the factice from the leather is not possible.

Man kann zum Tränken des Leders auch eine Mischung von Kautschuk und Ölen nebst Schwefelchlorür verwenden.You can also use a mixture of rubber and to soak the leather Use oils and sulfur chloride.

Daß ein so behandeltes Leder auch für andere Zwecke, z. B. für Lackiermaschinen, brauchbar ist, ist ohne weiteres verständlich.That leather treated in this way can also be used for other purposes, e.g. B. for painting machines, is useful is easily understandable.
