Description

Überzug für Druckereifarbwalzen Die Erfindung bezweckt, das Auftragen von Farbe auf Druckformen mittels Walzen, insbesondere beim Offsetdruck, vorteilhafter zu gestalten, als .es mit Hilfe der bekannten Leder- oder Massewalz-en stattfinden kann. Durch die Erfindung wird auch gegenüber der den Gegenstand eines Patents bildenden Verwendung von Walzen aus einem Gemische von Kautschuk und Faserstofferi zum Auftragen von Druckfarbe eine Vervollkommnung erzielt.Coating for printing ink rollers The invention aims at the application of color on printing forms by means of rollers, especially in offset printing, is more advantageous to design as .es take place with the help of the known leather or mass rollers can. The invention is also compared to the subject of a patent Use of rollers made from a mixture of rubber and fiber material for application achieved a perfection of printing ink.

Die Erfindung besteht darin,' daß als überzug für Druckereifarbwalzen eine filzige Masse verwendet wird, welche mit einer Lösung von NitroceZlulose oder einem verwandten Stoffe imprägniert ist.The invention consists in 'that as a coating for printing ink rollers a felty mass is used, which is mixed with a solution of NitroceZlulose or is impregnated with a related substance.

Bekannt ist es, Baumwolle oder Baumwollgewebe, die mit einem flüssigen Bindemittel gemischt sind, als Lederersatz zu verwenden und zu demselben Zwecke Wolle, die mit einer Lösung von. nitrierter Cellulose in Aceton getränkt ist, zu benutzen. Neu ist aber die Erfahrung, daß eine entsprechend imprägnierte Filzmasse gerade die Eigenschaften hat, welche für den überzug einer Walze zum Auftragen von Farbe auf Druckformen besonders wichtig sind.It is known, cotton or cotton fabric, which with a liquid Binders are mixed, to be used as a leather substitute and for the same purpose Wool made with a solution of. nitrated cellulose soaked in acetone, too use. What is new, however, is the experience that an appropriately impregnated felt mass just has the properties required for the coating of a roller for applying Color on printing forms are particularly important.

Die Herstellung der der Erfindung entsprechenden Walzen kann erfolgen, indem eine geeignete filzige Masse, z. B. gepreßter Wollfilz, in bekannter Weise mit einem Kern verbunden und hierauf mit einer Lösung von Acetylcellulose in Aceton getränkt wird, welche nach dein Verdunsten des Lösungsmittels eine fest mit den Fasern zusammenhängende elastische Masse zurückläßt.The rolls according to the invention can be manufactured by using a suitable felted mass, e.g. B. pressed wool felt in a known manner connected to a core and then with a solution of acetyl cellulose in acetone is soaked, which after your evaporation of the solvent a solid with the Leaves fibers coherent elastic mass.

Eine so hergestellte Walze, die nach dem Trocknen des Imprägniermittels in bekannter Weise abgeschliffen wird, um ihr eine genau zylindrische Form zu geben, besitzt, wie es für Farbwalzen erforderlich ist, eine durchaus gleichförmige Struktur, so daß sie die Farbe sehr gleichmäßig annimmt und wieder abgibt.A roller made in this way, which after the impregnating agent has dried is ground in a known way to give it an exactly cylindrical shape, has, as is necessary for inking rollers, a thoroughly uniform structure, so that it takes the color very evenly and releases it again.

Ein Quellen der Walzennasse bei Berührung mit Wasser oder den gebräuchlichen Waschmitteln für Farbwalzen sowie eine Lösung der Walzenmasse in Bestandteilen der Farbe oder anderen Stoffen, mit denen die Walze beim Drucken in Berührung kommen kann, findet nicht statt. Auch werden die Walzen nicht wie Lederwalzen im Laufe der Zeit gestreckt.A swelling of the roller wet on contact with water or the usual Detergents for inking rollers and a solution of the roller mass in components of the Ink or anything else the roller comes into contact with during printing can does not take place. Also, the rollers do not run like leather rollers stretched over time.

Zum Auftragen von Gelluloseesterdruckfärben sind die der Erfindung entsprechenden Walzen nicht verwendbar.For applying gelulose ester printing inks are those of the invention corresponding rollers cannot be used.
