Abstract:
A method of processing and packaging a photographic film, comprising the steps of:unreeling and cutting off a film roll of an elongate photographic photosensitive film and cutting off said elongate photographic photosensitive film to a predetermined length thereby to supply a sized film;positioning a spool and the sized film relatively to each other and coiling said sized film around said spool thereby to produce a film coil;rounding a cartridge blank sheet into a tubular form and crimping a cap on an end of the tubular form thereby to produce a single-open-ended cartridge;inserting said film coil into said single-open-ended cartridge, and thereafter crimping a cap on an opposite open end of said single-open-ended cartridge thereby to produce an assembled cartridge;placing said assembled cartridge into a case and mounting a case cap on an open end of said case thereby to manufacture a packaged product; andindividually discharging defective products produced in said processing and packaging method, such that said defective products are discharged without further processing;wherein said step of individually discharging said defective products includes the steps of:cutting off and discharging a defective region of said elongate photographic photosensitive film unreeled from said film roll;discharging a film coil having a winding length abnormality;discharging an assembled cartridge when its assembly is not according to predetermined parameters; anddischarging a defective case when an assembled cartridge cannot be fully inserted therein.
