SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL AND ITS WINDING METHOD

PROBLEM TO BE SOLVED: To obviate the occurrence of trouble, such as exposure, at the time of winding of a photosensitive material having a polyester base on a spool by providing the flanges of the spool with projecting parts for preventing the loosening in winding. SOLUTION: The flanges 2 of the spool 1 for winding the silver halide photographic sensitive material formed by using the polyester base has the projecting parts 3 for preventing the loosening in winding. The projecting parts 3 are 'overhangs' toward the inner side (photosensitive material side) of the flanges 2 and the height thereof is preferably 0.1 to 10mm, more preferably 0.2 to 7mm and further preferably 0.3 to 5mm. The height may be formed to all the same or the different. The overhangs may be formed on one of the flanges 2 or both thereof. The number thereof is preferably 1 to 50 points for one flange 2, more preferably 2 to 30 points and further preferably 2 to 10 points. The winding tension of the photosensitive material and the light shielding paper is preferably 1 to 100kg/m.
