Abstract:
A method of manufacturing different filmstrips from a long strip of continuous film, said filmstrips including first, second and third film types which have different lengths and numbers of perforations, said method comprising the steps of:designating one of said three film types using a designating device; selecting at least one of a plurality of punch holders of a die set device in accordance with a specific number of perforations corresponding to said designated film type, to make the number of perforations in one punching operation through said continuous film; setting a unit length for transporting the continuous film along a film path from said die set device toward a cutter, said unit length being determined from a specific length of said designated film type and a length of a cutting blank between said filmstrips in said continuous film; adjusting a length of said film path between said die set device and said cutter by using a movable roller disposed between first and second pass rollers, said movable roller being movable in a vertical direction and sustaining one of three predetermined positions, based on said three film types, by actuating an actuating mechanism, wherein said length of said film path is adjusted to a value that is a number of M times as long as said unit length, plus a length from a first end of each of said filmstrips to be cut at a cut position, to a first perforation to be made at a punching position in said each filmstrip; transporting said continuous film along said film path by said unit length; actuating said cutter and said selected at least one of said punch holders in synchronism with each other while said continuous film stops after each transport by said unit length; and performing side printing on said continuous film at a side print position which is set in a peripheral position of a first feed roller when said continuous film is passed between said first feed roller and a second feed roller; wherein said actuating said cutter cuts the continuous film to form individual filmstrips having said specific length, which respectively corresponds to the number of perforations per film type, wherein said filmstrips formed by said cutter include photographic filmstrips having at least a perforation per frame exposure location.
