Description

Das Verfahren dient dazu, bei Druckformen, die auf Folien hergestellt sind,' z. B. auf Zelluloid, Zellon o. dgl, die Enden der Folie nahtlos aneinander zu bringen, wie das bei einer Tiefdruckform erforderlich ist,· und ein •Wandern der Folie auf der Druckwake zu verhindern. Der Vorgang ist auf der Zeichnung dargestellt. Die Druckwalze α hat eine Nut.δ, die mit Zelluloid oder einem anderen, derThe method is used for printing forms that are made on foils, 'z. B. on celluloid, cellulose or the like, to bring the ends of the film seamlessly together, as is necessary with a gravure form, · and • to prevent the film from migrating on the print wake. The process is shown in the drawing. The pressure roller α has a Nut.δ, which is covered with celluloid or another that

ίο Druckfolie entsprechenden Stoffe ausgefüllt ist. Auf diese Nut wird zuerst das eine Ende c der Druckfolie c, c.1 aufgeklebt. Danach wird die Folie mittels Gegendruckwalze d aufgewalzt, indem man mit der Folie zwischen den Walzen α und d eine Platte e durchlaufen läßt. Das,Ende f dieser Platte ist so geformt, daß 'die Biegungen g und g1 genau der ,Krümmung der Druckwalze und Gegendruckwalze entsprechen.ίο the corresponding substances are filled in with the printing film. On this groove is first one end c of the printing film c, c. 1 glued on. The film is then rolled on by means of a counter-pressure roller d by letting the film pass through a plate e between the rollers α and d. The 'end f of this plate is shaped so that' the bends g and g 1 correspond exactly to the 'curvature of the pressure roller and counter pressure roller.

Hat die Druckwalze annähernd eine Umdrehung gemacht, so drückt die Biegung g das Folienende c1 fest auf die Füllung der Nut b. Die Biegung g1 bildet einen Gegendruck, weil sie sich an die Gegendruckwalze d anlegt. Wurde das Ende der Folie c1 während des Aufziehens, wenn die Folie z. B. aus Zelluloid· besteht, mit Azeton erweicht, so preßt sich das Ende dermaßen an das Zelluloid . in Nut b, und an das bereits vorher aufgeklebte Ende der Folie, daß eine nahtlose Endung entsteht und ein Wandern' oder Verschieben der Folie beim Drucken ausgeschlossen ist! >When the pressure roller has made approximately one revolution, the bend g presses the end of the film c 1 firmly onto the filling of the groove b. The bend g 1 forms a counterpressure because it rests against the counterpressure roller d . Was the end of the film c 1 during pulling when the film z. B. made of celluloid · is softened with acetone, so the end is pressed against the celluloid. in groove b, and to the end of the film that has already been glued on before, so that a seamless ending is created and the film cannot move or move when printing! >

Claims (2)

Patent-Ansprüche:Patent Claims: 1. Verfahren, als Druckform dienende Zelluloid- oder ähnliche. Folien nahtlos und unverrückbar auf eine Druckwalze aufzuziehen, dadurch gekennzeichnet, daß man in der Walze parallel zur Achse eine mit Zelluloid o. dgl. gefüllte Nut anbringt, auf der die beiden Enden der Folie aneinandergeklebt werden. . ·.1. Process, celluloid or similar used as printing form. Foils seamless and to be drawn immovably onto a pressure roller, characterized in that a groove filled with celluloid or the like is made in the roller parallel to the axis, on which the two ends of the film are glued together will. . ·. 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß durch eine Gegendruckwalze die Folie an die Druckwalze angepreßt und mit der Folie eine Platte zwischen den Walzen hindurchgeführt wird; die an ihrem Ende nach der Mantelfläche der Walzen gekrümmt ist, so daß sie die Endkante der Folie zum Kleben an die Druckwalze andrückt. ",2. The method according to claim 1, characterized in that by a counter-pressure roller the film is pressed against the pressure roller and a plate with the film is passed between the rollers; the one at its end after the lateral surface of the rollers is curved so that they can be the end edge of the film for gluing to the Pressure roller presses.
