ABSTRACT:
The inventive reel has two parts preferably made of plastic. One reel part comprises a first central hub section having a reel flange floatingly supported thereon, to move over the length of the first hub section between limits fixed by stops formed on opposite ends of the hub section. A parallel wire spring extends from the top of the first hub section to apply balanced forces against the floating flange, for biasing it to move toward the opposite reel flange. The second reel part comprises an integral flange and a second hub section upstanding thereon. A socket in the top of the second hub section seatingly receives the bottom of the first hub section. The reel is primarily designed for use with a tape or film strip which has a stiff leader which is slightly wider than the film itself. When the leader is placed between the two flanges, the floating flange must move against the urging of the wire spring to a spacing which securely captures the leader and loosely receives the tape or film between the flanges. The first reel, which has the floating flange, is removable from the assembly leaving the second reel which may be utilized in the threading of film which does not include a stiff leader required for automatic threading.
