ABSTRACT:
In a camera, a snag-and-drag web has one end portion secured to a take-up spool and an opposite free end portion provided with an integral hook. The web's free end portion initially protrudes into a nest adjacent a cartridge-receiving chamber, to make the free end portion bent to extend the hook away from the free end portion. When a film cartridge with a projecting film leader is loaded into the chamber, the hook engages the film leader. Rotation of the take-up spool then winds the snag-and-drag web onto the spool to move the hook to draw the film leader from the film cartridge and onto the spool.
