A photographic slide mounter cuts photographic film transparencies from a photographic film web and inserts the transparencies into slide mounts. A slide mount is advanced along a slide track to a position adjacent a knife where the slide mount is flexed to provide an insertion opening. The film web is advanced along a film track until a leading end of the web is partially inserted into the insertion opening.
