Claims (1)

Es ist allgemein bekannt und üblich, das Filmband durch Andruckrollen an den Transporttrommeln zu führen, um eine sichere Mitnahme des Filmbandes durch die Transporttrommeln zu erreichen.It is well known and customary to apply pressure rollers to the film tape on the transport drums to lead to a safe transport of the film tape through the transport drums to reach. Gegenstand der Erfindung isfeine besonders einfache Führung derartiger Andruckrollen bzw. Führungsrollen. Gemäß der Erfindung sind die Transporttrommeln mit einem Bund ίο versehen, der in eine Aussparung der auf ihrer Lagerachse lose angeordneten Andruckrollen eingreift und auf diese Weise die Andruckrollen gegen axiale Verschiebung sichert. In der Zeichnung ist ein Aus führ ungsbeispiel der Erfindung dargestellt, und zwar zeigtThe subject of the invention is particularly simple guidance of such pressure rollers or leadership roles. According to the invention, the transport drums are with a collar ίο provided in a recess of the pressure rollers loosely arranged on their bearing axis engages and in this way secures the pressure rollers against axial displacement. In the drawing, an exemplary embodiment of the invention is shown, namely shows Abb. ι die Anordnung der Transporttrommel und der Andruckrollen in Ansicht,Fig. Ι the arrangement of the transport drum and the pressure rollers in view, Abb. 2 in Aufsicht, und zwar gesehen in Pfeilrichtung A der Abb. 1.Fig. 2 in top view, seen in the direction of arrow A in Fig. 1. An der Werkplatte oder Gehäusewand 1 des Kino-Wiedergabeapparates (nicht dargestellt) ist in bekannter Weise die vom Kinowerk angetriebene Transporttrommel 2 angeordnet, die mit der Antriebswelle 3 fest verbunden ist. In der Nähe der Transporttrommel 2 sind auf in der Gehäusewand befestigten Achsen 4 und 5 Andruck- bzw·. Führungsrollen 6 und 7 lose gelagert.On the work plate or housing wall 1 of the cinema playback device (not shown) the transport drum 2 driven by the cinema is arranged in a known manner, which is firmly connected to the drive shaft 3. Near the transport drum 2 are on axles 4 and 5, which are attached to the housing wall, pressure or ·. Leadership roles 6 and 7 loosely stored. Gemäß der Erfindung werden die Andruckrollen dadurch gegen axiale Verschiebung gesichert, daß die Transporttrommel mit einem Bund 8 versehen ist, der in eine in den Andruckrollen vorgesehene Ringnut 9 eingreift. Durch diese Ausbildungsart wird eine wesentliche Vereinfachung sowohl in der Lagerung als auch im Zusammenbau der Rollen erzielt. Durch Lösen der Befestigungsschrauben 10 der Transportrolle können beispielsweise die beiden Rollen 6 und 7 ohne weiteres zusammen mit der Transporttrommel 2, vom Kino-Apparat entfernt werden.According to the invention, the pressure rollers are thereby against axial displacement secured that the transport drum is provided with a collar 8, which is in a Pressure rollers provided annular groove 9 engages. This type of training becomes a Significant simplification achieved both in the storage and in the assembly of the roles. By loosening the fastening screws 10 of the transport roller can, for example, the two rollers 6 and 7 without further together with the transport drum 2, can be removed from the cinema apparatus.
