ABSTRACT:
An automatic film takeup reel to capture the free end of a film and wind the end, must guide the film along a feed passage formed by a housing toward a rotating reel of a soft material. The end of the film is held to the reel by a ball biased by a spring toward the reel and is directed around a cavity until wound. A spring biased arm then shifts the housing axially of the reel to afford continued winding.
