ABSTRACT:
A reel assembly for feeding, receiving and storing flexible strip material such as motion picture film. The reel is adapted to be mounted on the feed or take up spindles for a movie projector and permits film wound on the reel to be unwound either from the outside of the film windings or from the inside. The reel assembly includes a hub with an integral radial flange at one side and a removable cover that fits over the hub and flange and surrounds the hub and the strip material wound thereon. A movable or free annular side plate is adapted to be retained by the cover opposite the radial flange. Located within the hub is a film extraction drum slidably received for axial movement between a retracted detent position within the hub and an axially extended position partially outside of the hub and extending through a central opening in the free side plate. The extraction drum has a fastening means thereon that is connectable to the tail end or inside end of film wound on the hub and which extends radially through a slot in the hub. When the extraction drum is moved axially outward to its extended position, it slides the tail end of the film strip laterally off of the hub so that the film strip may be unwound from the inside out while passing through the central opening in the free side plate. Thus, the film strip may be threaded through a movie projector and continuously fed even though it is unwinding unconventionally from the inside out.
