Description

Filmspule Die Erfindung geht aus von einer Filmspule für Filme geringer Länge, insbesondere für die Zwecke der Stehbildphotographie, mit einer den einen Filmrand überragenden, als Handgriff dienenden Verlängerung; und hat zur Aufgabe, das Befestigen des Films möglichst einfach und schnell ausführbar zu gestalten.Film reel The invention is based on a film reel for films less Length, especially for the purposes of still photography, with one of the one Extension protruding from the edge of the film and serving as a handle; and has the task to make the attachment of the film as easy and quick as possible.

Erfindungsgemäß, besteht daher die Spule aus einem axial in den Filmwickel einschiebbaren Rohrstück mit .einer zur Spulenachse parallelen Klemmfeder zum Festklemmen des Films.According to the invention, therefore, the spool consists of an axially inserted film roll Insertable pipe section with a clamping spring parallel to the coil axis for clamping of the film.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar in Abb. i in Ansicht und in Abb.2 im Längsschnitt.In the drawing, the invention is shown in an exemplary embodiment, namely in Fig. i in view and in Fig. 2 in longitudinal section.

An dem Rohrstück i ist eine Blattfeder 2 befestigt, die mit ihrem freien Ende bei dem kegelig gehaltenen Rohrende 3 endet und die so lang ist, daß sich der Film q. in t seiner ganzen Breite unterschieben läßt.A leaf spring 2 is attached to the pipe section i, with its free end ends at the conically held pipe end 3 and which is so long that the movie q. can be inserted in t across its entire width.

Will man den Filmstreifen q. an der Spule i befestigen, so ist es nur nötig, die Spule so über die innerste Windung des Filmstreifens 4 zu schieben, daß. sich hierbei der Film zwischen Feder 2 und Rohrwand klemmt: Da das untere Rohrende 3 kegelig gehalten ist, gleitet der Film leicht unter die Feder. Darauf wird die Spule in bekannter Weise auf den Spülenträger 5 gesteckt. Diese Filmspule läßt sich in gleicher Weise wie bei Bildwerfern auch bei Vergrößerüngs- und Kopiergeräten verwenden.Do you want the film strip q. attach to coil i, so it is only necessary to push the spool over the innermost turn of the film strip 4, that. Here the film is jammed between the spring 2 and the pipe wall: Because the lower end of the pipe 3 is tapered, the film slides easily under the spring. Then the Coil plugged onto the sink support 5 in a known manner. This film reel can in the same way as with projectors, also with enlargers and copiers use.
