  Vorrichtung zum Reinigen von   Filmbändern   mittels umlaufender Bürstwalzen. 



   Die bisher übliche Reinigung von Filmbändern mittels umlaufender Bürstwalzen ist insofern noch unvollkommen, als die Walzen zwar bei ihrem Umlauf den Film von Staub u. dgl. Unreinigkeiten befreien, selbst jedoch nach und nach'verstauben und so bei längerem Gebrauch der Vorrichtung nicht zu vermeiden ist, dass Staubteilchen von den   Bürsten   wieder auf den sich weiterbewegenden Film übertragen werden und an diesem haften bleiben. 



   Gemäss der Erfindung sind die Bürstwalzen in einem an eine Saugleitung angeschlossenen Gehäuse untergebracht, so dass nicht nur der von dem Film abgenommene, sondern auch etwa an den Bürstenumfang selbst sich ansetzender Staub ununterbrochen abgeleitet wird. Auf diese Weise ist somit Gewähr dafür geboten, dass stets vollkommen staubfreie Bürstenwandungen zu beiden Seiten des Films auf diesen einwirken, dieser also vollständig gereinigt der Aufwickelrolle zugeführt werden kann. 



   Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes, wobei Fig. i einen senkrechten Schnitt, Fig. 2 eine Seitenansicht des die Bürstwalzen umschliessenden Gehäuses in kleinerem Massstabe zeigen. a bezeichnet den Film und b, b in entgegengesetzten Richtungen umlaufende Bürstwalzen, deren Achsen, was gleichfalls an sich bekannt ist, parallel zur Fortbewegungsrichtung des Films liegen. Der Antrieb der Bürstwalzen kann in beliebiger Weise z. B. durch die in entgegengesetzten Richtungen angetriebenen Zahnräder   d   erfolgen, die mit Zahnrädern c der Walzenachsen in Eingriff stehen.

  Device for cleaning film tapes by means of rotating brush rollers.



   The previously common cleaning of film strips by means of rotating brush rollers is still imperfect, as the rollers, although the film from dust u. Like. Remove impurities, but gradually dust themselves and so with prolonged use of the device it cannot be avoided that dust particles are transferred from the brushes again to the moving film and adhere to it.



   According to the invention, the brush rollers are accommodated in a housing connected to a suction line, so that not only the dust removed from the film, but also, for example, on the brush circumference itself, is drained off continuously. In this way, there is a guarantee that completely dust-free brush walls on both sides of the film always act on the film, that is to say that it can be fed to the take-up roll in a completely cleaned state.



   The drawing illustrates an embodiment of the subject matter of the invention, FIG. 1 showing a vertical section and FIG. 2 showing a side view of the housing enclosing the brush rollers on a smaller scale. a denotes the film and b, b are brush rollers rotating in opposite directions whose axes, which is also known per se, are parallel to the direction of movement of the film. The drive of the brush rollers can be used in any way, for. B. done by the gear wheels d driven in opposite directions, which are in engagement with gear wheels c of the roller axles.
