Title: Film guide for use with film cleaning apparatus

Abstract: A film cleaning apparatus for cleaning the photographic film prior to printing includes special guides which permit the film cleaning apparatus to be used with both first-run production and tabbed reprint production. The film cleaning apparatus is of the type having a pair of support members in opposed relationship which define a nip which is disposed transverse to the path of the photographic film. Two lengths of soft, lint-free wiping cloth extend through the nip with the opposed surfaces of the cloth at the nip defining a part of the path. The guide includes first and second generally parallel guide plates having opposing surfaces defining an opening which is part of the path. The opening defined by the guide plates has an inlet end and an outlet end, and the plates are in fixed position with respect to the film cleaning apparatus with the outlet end of the opening proximate the nip. A first member is positioned forward and above the inlet end of the opening for guiding film downward toward the inlet end, and a second member is positioned forward and below the inlet end for guiding film upward toward the inlet end. The film guide, therefore, permits reliable feeding and guiding of short film segments attached to a paper tab like those used in photographic reprint systems.
