Method and apparatus for manufacturing photographic film and photographic film cassette.

摘要

In a photographic film cassette manufacturing apparatus, a perforator (7) for providing a long film (15) with perforations and a cutter (21) for cutting the long film into individual filmstrip to be contained in the film cassette are driven synchronously with transport of the long film. A magnetic recording head (19) for recording data on a magnetic recording layer of the long film is driven in synchronism with the perforator or the cutter. The long film is transported in a first direction before being cut into the individual filmstrips. In cooperation with the cutting, the trailing end of the individual filmstrip in the first direction is held to be displaced from the long film transport path, and moved in the reverse of the first direction so as to secure the trailing end to the spool. A cassette shell (3) consisting of a pair of shell halves is temporarily assembled by mating the shell halves together while containing a spool inside the shell halves, and thereafter opened to an extent that confining elements still confine the flanges of the spool. The trailing end of the filmstrip is inserted into the opened cassette shell and secured to the spool. Then, the shell halves are mated together again and the spool is rotated so as to wind the filmstrip into the closed cassette shell.
