Description

Nach dem Patent 509 672 wird die Zusatzgeschwindigkeit des Films durch das schwingende Fenster mit einer Rolle durch Umlegen des Films um einen Teil der Nachwickelrolle bestimmt, so daß die Bewegung des Fensters nur einen Teil der Bildhöhe beträgt.According to the patent 509 672, the additional speed of the film through the swinging window with a roll by flipping it of the film around part of the rewind roller determined so that the movement of the window is only part of the image height.

Um den Weg des Fensters weiter abzukürzen, werden erfindungsgemäß an demselben anstatt einer mehrere Rollen mitschwingend angeordnet und zugleich am Gehäuse festsitzende Hilfsrollen angebracht, so daß sich der Film jetzt nicht nur um einen Teil der Nachwickelrolle legt, sondern auch um Teile der dazwAschenlagernden Hiilfsrollen. Mit dieser Anordnung werden bei jeder Hinundherbewegung des Bildfensters mehrere Schleifen gebildet und wieder aufgelöst, was zur Folge hat, daß die Zusatzgeschwindigkeit je nach der Anzahl der angebrachten Rollen beliebig gesteigert werden kann.In order to shorten the path of the window further, according to the invention, the same instead of one, several roles are arranged swinging along and at the same time fixed auxiliary roles are attached to the housing, see above that the film now not only wraps itself around part of the rewind roll, but also for parts of the auxiliary rolls stored in between. With this arrangement, several loops are formed and dissolved again with each movement of the image window. with the consequence that the additional speed depends on the number of attached Roles can be increased at will.

Die Zeichnungen stellen ein Ausführungsbeispiel dar. The drawings represent an exemplary embodiment.

Beispiel. Die Wirkungsweise des Apparates ist in dem Hauptpatent 509 672 beschrieben, nur ändert sich die Anzahl der Rollen. Es bilden bei dieser Anordnung die am Fenster mitschwingend angeordneten Rollen L1 M mehrere Schleifen durch Umlegen sowohl um einen Teil der Nachwiickelrolle E als auch um Teile der fest am Gehäuse angebrachten Hilfsrolle N, so daß dadurch eine größere Zusatzgescbwindigkeit erreicht wird.Example. The operation of the device is described in the main patent 509 672, only the number of roles changes. In this arrangement, the rollers L 1 M, which are arranged swinging along the window, form several loops by turning both around part of the rewinding roller E and around parts of the auxiliary roller N fixed to the housing, so that a greater additional speed is achieved.

Die Zahl der Rollen und Hilfsrollen kann beliebig vergrößert werden.The number of roles and auxiliary roles can be increased as required.
