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bonded to the film leader by electostatic attraction properties whereby the film leader is then able to be extracted or withdrawn from the film canister.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.
Claims20
Apparatus for withdrawing a portion of a member from a holder thereof, which portion is attracted to statically charged material, said apparatus comprising:
- a body;
- and means on said body for carrying a static charge for electrostatically adhering to the portion with sufficient force for withdrawing the portion from the holder.
A film extractor implement for extracting a film leader portion of a photographic film disposed within a photographic film canister, comprising:
- a structural stiffener member;
- and
- a static-cling vinyl member mounted upon said structural stiffener member for developing a static-cling attraction to a film leader portion of a photographic film, disposed within a photographic film canister, when said film extractor implement is inserted into the photographic film canister so as to temporarily bond with the film leader portion of the photographic film whereby the film leader portion of the photographic film is able to be extracted from the photographic film canister when the film extractor implement is withdrawn from the photographic film canister.
A film extractor component for use with a hook-type film extractor implement for extracting a film leader portion of a photographic film disposed within a photographic film canister, comprising:
- a tab member;
- means disposed upon said tab member for securing said tab member to a film leader portion of a photographic film disposed within a photographic film canister;
- and
- aperture means defined within said tab member for engagement by a hook-type film extractor implement such that when a hook-type film extractor implement is inserted into the photographic film canister, said aperture means of said tab member is able to be engaged by the hook-type film extractor implement whereby the film leader portion of the photographic film disposed within the photographic film canister is able to be extracted from the photographic film canister when the hook-type film extractor implement is withdrawn from the photographic film canister.
A film extractor system for extracting a film leader portion of a photographic film disposed within a photographic film canister, comprising:
- a tab member;
- means disposed upon said tab member for securing said tab member to a film leader portion of a photographic film disposed within a photographic film canister;
- aperture means defined within said tab member;
- and
- a film extractor implement having hook means disposed thereon for engagement with said aperture means of said tab member such that when said film extractor implement is inserted into the photographic film canister, said hook means of said film extractor implement can engage said aperture means of said tab member whereby upon withdrawal of said film extractor implement from the photographic film canister, the film leader portion of the photographic film disposed within the photographic film canister can be extracted therefrom.
A method of extracting a leading end portion of a coiled photographic film in a cassette having a film withdrawal slot;
- said method comprising the steps of:
- inserting a withdrawing body into the slot such that means thereon for carrying an electrostatic charge is engaged with the film so as to effect an electostatic bonding therebetween with sufficient force to allow extraction of the leading portion by applying a withdrawing force to the withdrawing body.
