Film patch, jig and method of using same

The present invention relates to a patch which is easily applied to motion picture film, a jig and a method for using the same. The patch may act as a splice to connect two lengths of film which require repair or which must be joined together to produce a complete presentation. The patch may also be applied along a predetermined position of the film to carry control information which may be used to control the sequence of events in a movie theater. In some applications, the patch may serve both a splicing as well as an information-carrying function. The patch can be rapidly and accurately positioned and attached to the film by use of a novel splicing jig and results in a splice which does not leave any adhesive residue about the film sprocket holes or on the jig.

Method and apparatus for checking film-cutting positions

A method and apparatus for determining whether a predetermined cut position lies within an unexposed portion of a roll of film is provided. A first density sensor 20 senses film density of a roll of film (10) and produces film density data. The film density data is stored in a first data storage device (50). A second data storage device (52) reads and stores a film density data value indicative of the lowest value of the film density stored in the first data storage device (50) and outputs this as base density data. A second density sensor (22) senses the film density at a predetermined cut position and produces cut position density data. A counter (66) counts pulses produced by a film drive and, when a predetermined number of pulses has been counted, indicating the arrival of the film at the predetermined cut position, the counter (66) produces a control signal that causes a comparator (26) to compare the base density data to the cut position density data. The comparator (26) produces a cutter control signal that causes a film cutter to cut the film (10) at the predetermined cut position only when the value of the cut position density data indicates that the film density at the cut position is within a predetermined range of the base density. In a typical installation, the film is comprised of several rolls of film spliced together. The invention includes a first splice detector (54) that detects a splice at a first time and a second splice detector (56) that detects the splice at a second subsequent time to identify each roll of film. The base density information is then keyed to a particular roll of film.

Induction splicing of photographic film strips

A method is described for splicing together overlapping ends of first and second lengths of photographic film strips of common film strip width, comprising positioning a bonding element between an overlapping end of the first length of photographic film and a corresponding overlapped end of the second length of photographic film, and heating the bonding element to effect an adhesive bond between such film ends, wherein the bonding element comprises an induction heating receptive support and thermoplastic adhesive layers on each side of the support, and wherein the heating of the bonding element is performed by induction heating. The present invention allows for the preparation of photographic film splices, consisting of either homogeneous or dissimilar film bases, using a bonding element and induction heating to provide smooth yet strong splices. In particular, the invention enables successful splicing of acetate support (e.g., cellulose triacetate (CTA)) based films and polyester support (e.g., polyethylene terephthalate (PET)) based films either to themselves or each other. The invention provides a method of forming composite rolls of motion picture film containing different film bases as well as eliminating the need for emulsion skiving, and the use of toxic, flammable film cements when splicing CTA films.

Method for splicing web end portions with plastic rivets

Web end portions are spliced together with plastic rivets formed from a soft pliable plastic. To form a splice, a patch of thermoplastic having the property of expanding when subjected to heat and pressure such as chlorinated polyethylene material, is placed on a splicing base. A pair of web end portions to be spliced together are placed in abutting or overlapped relation on the platic material to form a web-patch sandwich. A platen having an opening in register with the patch is brought into pressure engagement with the web-patch sandwich to form a pressurized plastic bubble extending into the opening. A heated pin of substantially the same configuration as the opening is moved therethrough for confining the opening and inserting a necked down head at the end thereof into the plastic in the bubble. The combination of heat, pressure and gas formation within the thermoplastic causes the visco-elastic plastic to expand through the opening in the web formed by the pinhead to fill the confined opening and form a plastic rivet head on the surface of the web opposite the patch.
