  • Patent number: 5848316
    Abstract: A film leader extractor comprises, in accordance with a first embodiment of the invention, a structural stiffener component or member having a static-cling vinyl component or member laminated thereto by a suitable adhesive. When the extractor is inserted into, for example a 35 mm photographic film cartridge or canister, the static-cling vinyl layer is temporarily bonded to the film leader by electostatic attraction properties whereby the film leader is then able to be extracted or withdrawn from the film canister. In accordance with a second embodiment of the invention, a tab member is adhesively bonded to the film leader. The tab member is provided with an enlarged aperture to be engaged with a hook-type extractor implement.
