ABSTRACT:
A precut strip of 35 mm. photographic film 5 is wound onto a magazine spool 3 by inserting the leading end of the film strip into an aligned spool slot 3a, rotating the spool to wind the film strip thereon, enclosing the wound spool with an open slotted cylindrical cover or shell 4, pinch or squeeze closing the cover slot, and placing caps 1, 2 over the open ends of the cover. A plurality of apparatusses 7 for automatically implementing the above steps are mounted at spaced positions on a continuously moving endless conveyor 6 disposed adjacent a plurality of stationary cams which controllingly engage followers on the apparatusses during the conveyor movement, and all of the work operations are performed on the same moving spool shaft axes, whereby greatly increased production speeds are possible.
