Abstract
An apparatus for removing foreign matter from a flexible support such as a photographic film or magnetic tape. After applying a solvent to the surface of the support from which the foreign matter is to be removed, the support is passed over at least two parallel adjacent plates which extend widthwise perpendicular to the direction of movement of the support, with the plates being located relative to the support at a position before the solvent evaporates. The edge surface of the downstream one of the two plates is provided with a cutting edge at the upstream side thereof. The cutting edge forms a gap with the surface sufficiently small that the foreign matter to be removed cannot enter the gap. Further, the gap is large enough to leave solvent film in a thickness of at least 0.2 microns after passing the two plates.
