ABSTRACT:
A reel is provided for the winding and unwinding of wire or the like. The reel includes a cylindrical hub having a pair of flanges, one at each end of the hub. The hub includes an inner cylindrical wall defining a central hollow bore through the center of the reel. An outer cylindrical wall is provided concentrically around the inner wall and forms a barrel surface for the winding of the coiled wire (or the like) thereon. The flanges serve to protect the wire wound on the barrel surface. A frusto-conical or tapered wall is provided at opposite ends of the reel to connect the inner wall of the hub to the radially projecting flange. The frusto-conical wall includes at least one opening or window therein, providing a handle for lifting the reel from a package or carton. The reel may also be provided with a series of concentric cylindrical support ribs within the hollow portion defined by the flanges. Other structural support members may also be provided by the internal structures of the reel.
