Description

Die Erfindung bezieht sich auf ein Gerät zum Schneiden von Filmbändern, in dem erfindungsgemäß eine Schneidvorrichtung mit einer Vorrichtung zum Anrauhen der Enden der zu klebenden Filmbänder vereinigt ist. Durch besondere Vorrichtungen, Führungsleisten und Anschlagstifte wird die richtige Lage des Filmbands gewährleistet. Zum Festhalten des Films beim Anrauhen dient ein schwenkbares Haltelineal.The invention relates to a device for cutting film tapes, in which according to the invention a cutting device with a device for roughening the ends of the film tapes to be glued is united. By special devices, Guide strips and stop pins ensure the correct position of the film tape. A swiveling ruler is used to hold the film in place while roughening.

Der in Abb. i und 2 dargestellte Erfindungsgegenstand besteht aus dem Gehäuse a, in das eine Lichtquelle b, Glühlampe o. dgl., eingebaut ist. Am Gehäuse a ist der Schneidmesserhalter c mit Messer d beispielsweise schwenkbar befestigt.The subject of the invention shown in Fig. I and 2 consists of the housing a, in which a light source b, incandescent lamp o. The like., Is built. The cutting knife holder c with knife d is, for example, pivotably attached to the housing a.

Entsteht bei der Vorführung von Filmen ein Filmriß oder werden bei der Kontrolle schlechte Klebestellen, Perforationsschäden festgestellt, so müssen diese Stellen ausgeschnitten und für das Wiederzusammenkleben vorbereitet werden.Does a film tear occur during the showing of films or are there at the inspection has found bad joints, perforation damage, so must these areas are cut out and prepared for gluing back together.

Diese Vorbereitung geschieht bislang nach Augenmaß, wobei grobe Fehler durch Leichtsinn, Unachtsamkeit u. dgl. unvermeidbar sind, die zu großem wirtschaftlichen Schaden führen können. Die Erfindung, Gerät zum Schneiden und Anrauhen von Filmbändern, schaltet die menschliche Unzulänglichkeit aus.This preparation has so far been done with a sense of proportion, with gross errors are unavoidable through carelessness, carelessness and the like, which lead to great economic Can cause harm. The invention, device for cutting and roughening film tapes, eliminates human inadequacy.

Der beschädigte Filmstreifen e wird mit seinen Perforationsausschnitten so in die Längsanschläge g der Schneidauflage feingelegt, daß ein Bildstrich h über dem von der Lichtquelle b beleuchteten Lichtschacht i zu stehen kommt. Queranschlagleiste k sichert das winkelrechte Beschneiden des Filmstreifens e durch Schwenken des Messerhalters c.The damaged film strip e is with its perforation cutouts so finely placed in the longitudinal stops g of the cutting support that a line h across the light shaft i illuminated by the light source b comes to a stand. Cross stop bar k ensures that the film strip e is trimmed at right angles by pivoting the knife holder c.

Der Längenabstand der Perforationslängsanschläge g bis zum Schneidmesser d ist so angeordnet, daß stets die gleiche Klebeüberlappung 1 gewährleistet ist. Damit ein Zusammenkleben der beiden beschnittenen Filmenden möglich ist, muß an einem Ende die photographische Schicht entfernt, das andere Ende, die Glanzseite, angerauht werden, um einwandfreies Kleben zu ermöglichen. Das Anrauhen der Glanzseite und das Abschaben der photographischen Schicht der Klebeüberlappung L geschieht durch Einlegen des Filmstreifens e in die Schabeauflage, in derselben Weise wie in die Schneidauflage. Die zu schabenden Überlappungen L werden durch Lichtquelle b und Lichtschacht i, der Bildstrich h erkennen läßt, beleuchtet, Perforationslängsanschläge g sichern mit den Queranschlagleisten k die gleiche t`berlappungslänge l und winkelrechte Auflage, so daß das Abschaben mit Hilfe des drehbar gelagerten Haltelineals n auf durchsichtiger Schabeunterlage o, Glas o. dgl., die durch Lichtschacht i beleuchtet ist, durchgeführt werden kann.The length spacing of the longitudinal perforation stops g to the cutting knife d is arranged so that the same adhesive overlap 1 is always guaranteed. So that the two trimmed ends of the film can be glued together, the photographic layer must be removed from one end and the other end, the glossy side, must be roughened to enable perfect gluing. The roughening of the glossy side and the scraping off of the photographic layer of the adhesive overlap L is done by inserting the film strip e into the scraping support, in the same way as in the cutting support. The overlaps L to be scraped are illuminated by light source b and light shaft i, the line h can be seen in the picture, longitudinal perforation stops g secure the same overlap length l with the transverse stop strips k, so that scraping can be carried out with the help of the rotatably mounted retaining ruler n transparent scraping pad o, glass o. The like. Which is illuminated by light shaft i, can be carried out.
