Method and apparatus for winding a photographic film and photographic film manufacturing apparatus

摘要

A winding mechanism (100) for winding a narrower web (24) has a drive shaft (104) with a torque transmitting member (106) fixedly mounted thereon, and a holder (116) rotatably mounted on the drive shaft (104) with a spring (156) disposed around an outer circumferential surface (138) of the holder (116) with cushioning members (142a through 142c) interposed therebetween. Stoppers (154) are disposed respectively in three chambers (146a through 146c) defined in the holder (116). A groove (204) is defined in an inner circumferential surface (202) of a winding core (200) around which the narrower web (24) is wound, and the cushioning members (142a through 142c) are fitted in the groove (204). A pressing force of the spring (156) is applied through the stoppers (154) to the winding core (200) which is mounted on the holder (116).
