Description

Verfahren zur Herstellung eines Dreifarbenfilms` Bei der Herstellung von Dreifarbenfilmen ergeben sich Schwierigkeitun dadurch, daß die drei Teilbilder nicht genau übereinanderpass(#II, so daß bei der Vorführung Farbenränder entstehen. Dieser Nachteil ist darauf zurückzuführen, daß bei der Herstellung des Films zu seiner Fortschaltung die normale Perforation mit länglichen Löchern benutzt wird, in welchen die Greifer ein gewisses Spiel haben. Bei dem wiederholten Begießen des Films mit Emulsion wird der Film selbst Größenveränderungen unterworfen, und hierdurch sowie durch das Spiel der Greifer in den Durchbrechungen des Films ergibt sich dann die ungenaue Überdeckung der Teilbilder.Method of making a three-color film` During manufacture of three-color films, difficulties arise in that the three partial images not exactly on top of each other (#II, so that colored borders appear during the demonstration. This disadvantage is due to the fact that in the manufacture of the film too the normal perforation with elongated holes is used in its progression, in which the grippers have a certain amount of play. With repeated watering of the Film with emulsion changes the size of the film itself, and thereby as well as the play of the grippers in the openings in the film then results the imprecise coverage of the partial images.

Der Zweck der Erfindung ist nun, diesen Nachteil zu beseitigen und ein Verfahren zur Herstellung eines in jederBeziebung einwandfreien Films zu schaffen.The purpose of the invention is now to eliminate this disadvantage and to provide a method for producing a film that is satisfactory in every respect.

Bei der Herstellung eines Dreifarbenfilms nach der Erfindung wird zunächst in einemz beiderseitig begossenen Positivfilm eine Perforation mit kreisförrnigen Löchern vorgesehen, wobei der Durchmesser dieser Löcher geringer ist als die Höhe der ',\-ormalperforation. Während der Aufbringung der Teilbilder auf die beiden Schichten wird der Film durch Greiferpaare fortgeschaltet, deren Greifer im Otierschnitt kreisf#3rmig ausgebildet und an Jen freien Enden zugespitzt sind. Die Greifer passen genau in die Löcher der Perforation, so daß ein genaues Überdecken. der Teilbilder mit Sicherheit gewährleistet wird. Der soweit bearbeitete Film wird dann mit der dritten Emulsionsschicht versehen, und erst dann wird die normale Perforation einge - stanzt, worauf alsdann der Film durch die üblichen Greifer fortgeschaltet wird.In the production of a three-color film according to the invention, a perforation with circular holes is first provided in a positive film cast on both sides, the diameter of these holes being smaller than the height of the ', \ - ormalperforation. During the application of the partial images to the two layers, the film is advanced by pairs of grippers, the grippers of which are circular in shape and are pointed at the free ends. The grippers fit exactly into the holes of the perforation, so that an exact covering. the partial images is guaranteed with certainty. The extent processed film is then provided with the third emulsion layer, and then the normal perforation is - punch, whereupon the film is then incremented by the usual gripper is.
