DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing a photographic roll film in which a photographic film strip and a light-shielding paper strip are wound around a spool.

[0002]

2. Description of the Related Art In general, 12 rolls are used for photographic roll films.
There are types called type 0 and type 220. 120
The type of photographic roll film includes a spool, a photographic film strip wrapped around the spool, a light-shielding paper strip wrapped around the spool together as a backing of the photographic film strip, and a light-shielding paper strip at the end of the photographic film strip. Adhesive tape to be fixed to the back side of the photo film strip, an opening seal wrapped around the outer periphery of the light-shielding paper strip to prevent loosening of the photographic film strip and the light-shielding paper strip wound around the spool, and wrapped around another spool after shooting And a sealing seal used to prevent the loosening of the photographic film strip and the light-shielding paper strip.

[0003] The 220 type photographic roll film is
The structure is almost the same as that of the 120 type, but the backing paper is eliminated and the leader and trailer made of the same material as the light-shielding paper strip are attached to the leading and trailing ends of the photo film strip with adhesive tape. The length of the photo film strip wound around the spool is increased to increase the number of shots.

[0004]

In a conventional photographic roll film, when a light-shielding paper strip and a photographic film strip are wound on a spool, they are wound on the light-shielding paper strip without applying a back tension. for that reason,
In some cases, the light-shielding paper strip meandered and got on the flange of the spool. If one edge of the light-shielding paper strip runs over the flange, the roll diameter of the photographic roll film becomes large, resulting in a defective product or a light-shielding defect.

Further, since the back tension is not applied to the light-shielding paper strip, the light-shielding paper strip and the photographic film strip are loosely wound around the spool. As a result, the light-shielding paper strip and the photographic film strip are wound and squeezed when the opening seal is wound around the outer periphery of the light-shielding paper strip that has been wound.
In the case of the 0 type, the photo film and the light-shielding paper or the light-shielding papers are rubbed, and in the case of the 220 type, the photo film and the light-shielding paper, or between the photo films or the light-shielding papers are rubbed. As a result, there is also a problem that irregularities on the printing surface of the light-shielding paper and foreign matters such as paper dust and emulsion dust cause scratches on the emulsion surface of the photographic film strip, resulting in a fatal defect on the product.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to prevent improper winding of a light-shielding paper strip and a photographic film strip on a spool and to prevent scratches on the photographic film strip.
