ABSTRACT:
A ribbon adhering apparatus for a photographic film cassette has a turntable, which has holders fixed circumferentially at a regular pitch. Slidable supporters are mounted on the turntable in correspondence to the respective holders, at positions inward therefrom. Initially in rotation of the turntable, a cassette half of a film cassette is set on an empty holder. Ribbon web is lapped on to support surfaces of supporters arranged adjacently. The web is cut between the supporters to separate ribbons. Sucked and held on the supporter, the ribbon is then heated to activate hot-melt adhesive agent. By advancing the supporter to a holder corresponding thereto, the ribbon is pressed against the cassette half via the adhesive agent. The supporter then stops holding the ribbon. After cooling the adhesive agent, the supporter is withdrawn from the holder, from which the cassette half is removed.
