ABSTRACT:
A reel for tapes and film strips is formed with a hub which extends between a pair of flanges. A section of the surface of the hub is moveable relative to the remainder of the hub so that the end of a tape or film strip can be inserted between the removeable and the remaining portion, there to be clamped whereby winding of the tape on the reel is facilitated. In one form of the invention that separable section is hinged so that it can be tilted and removed from the space between the flanges through a window in one of the flanges. In another form of the invention, the removeable section of the hub surface has the form of a clamp which is cammed to open and closed to position by movement radially relative to the hub.
