ohne weiteres auf den Stiften bewegt werden kann. Ferner ist in dem Führungsstück 7c eine Buchse o angeordnet, die innen mit Gewinde versehen ist und eine Schraube p trägt. An dem freien Ende der Schraube p ist eine Feder q befestigt. Diese Feder q, welche in einer durchgehenden Bohrung r der Be- festigungsleiste d eingesetzt ist, wird mit dem andern Ende an einem dazu ausgebildeten an dein Führungsteil l befestigten Stift s eingehängt. Das Führungsstück l besitzt ebenso wie das federnde
EMI2.2
und u'. Um nun diesen Führungsteil l fest einstellen zu können, ist eine gegen den Stift t drückende Schraube v in den Führungsteils angeordnet.
Die Rolle c ist also wie die Rolle b zunächst auch federnd, wird aber durch die gegen den Stift t drückende Schraube v festgestellt, so dass sie eine federnde Wirkung nicht ausüben kann. Dadurch kann der Film genau zur Fortschaltrolle eingestellt werden. Soll der seitliche Druck der federnden Rolle b vergrössert oder verkleinert werden, so braucht nur die Schraube p durch Drehen der Buchse o entsprechend verstellt werden. Es kann also durch die Buchse o der Druck auf das Filmband genau abgestimmt werden, wodurch seitliche Pressungen des Films vermieden werden.
PATENT-ANSPRÜCHE : 1, Filmbandführung zur Vermeidung seitlicher Bewegungen des Filmbandes im Bildfenster an Kinoapparaten, gekennzeichnet durch zwei oberhalb des Bildfensters in einer Ebene quer zur Laufrichtung des Filmbandes vorgesehene, um eine Achse bewegliche Führungsstücke, wovon das eine verstellbar und das an :'. ere federnd mit einer Spannvorrichtung versehen ist.

can be easily moved on the pins. Furthermore, a bush o is arranged in the guide piece 7c, which is internally threaded and carries a screw p. A spring q is attached to the free end of the screw p. This spring q, which is inserted into a through hole r of the fastening strip d, is hung with the other end on a pin s which is designed for this purpose and which is fastened to the guide part l. The guide piece l has just like the resilient one

and u '. In order to be able to set this guide part l firmly, a screw v pressing against the pin t is arranged in the guide part.
The roller c, like the roller b, is initially also resilient, but is fixed by the screw v pressing against the pin t so that it cannot exert a resilient effect. This allows the film to be set precisely for the advance roll. If the lateral pressure of the resilient roller b is to be increased or decreased, only the screw p needs to be adjusted accordingly by turning the bush o. The pressure on the film tape can therefore be precisely matched through the socket o, as a result of which lateral compression of the film is avoided.
PATENT CLAIMS: 1, film tape guide to avoid lateral movements of the film tape in the picture window on cinema sets, characterized by two guide pieces provided above the picture window in a plane transverse to the direction of travel of the film tape, movable around an axis, one of which is adjustable and the other to: '. ere is resiliently provided with a clamping device.
