ABSTRACT:
A cleaning device for removing dust particles and other impurities from the surface of data carriers such as photographic film. Two counter-rotating brushes sweep across the film surface to remove the impurities while air flows on either side of the film sweep away the impurities. The air flows are created by two counter-rotating fans, the armatures of which also rotate the brushes. The fans remove the need for a separate vacuum source. A slot facilitates the passage of the film through the brushes while a static eliminator removes charged particles from the film after it exits the brushes. The stiff brushes aid in overcoming static charges that may be on the film surface.
In a further embodiment only one of the two brushes is driven by a fan and the other brush rotates freely and is biased toward the driven brush.
