Abstract
Automatic and semi-automatic slide mounters sever individual film transparencies from a photographic film web to prepare photographic slides therefor. The present invention relates to an apparatus for severing the individual film transparencies from the photographic film web in a slide mounter. The apparatus includes a movable knife assembly adapted for longitudinal adjustment and having a gauge for establishing an adjusted position for upper and lower knife blades therefor. The movable knife assembly is adjusted prior to operation to assure that the individual film transparencies of the film web will be correctly severed along film frame delineations for the individual film transparencies when advanced for operation across upper and lower knife blades of the knife assembly.
