Abstract
A reel may be fabricated from three flat pieces of die-cut cardboard wherein the center or hub section is defined by laterally projecting tabs from a longitudinal strip. The tabs fit through pairs of slots defined in the side members of the reel. The entire construction may thus be fabricated from a flat stock material that is recyclable.

A reel for support of a rope of material wound on said reel, said reel being recyclable and comprised of an assembly of three flat planar recyclable members folded and assembled into a reel configuration, comprising in combination:
- first and second side members, each member having an inside and an outside, said first and second side members having a center point, at least three substantially congruent, equally radially spaced pairs of slots, each of said pairs of slots characterized by an inner radial slot and an outer radial slot;
- a hub section formed of a longitudinal strip with generally parallel, longitudinal side edges, said side edges having a length generally greater than the circumference of a hub for the assembled reel, and at least three pairs of tabs, each pair comprised of a first tab and a second tab, one of which extends laterally from one side edge and the other of which extends from the other side edge, said pairs of tabs spaced along the side edges so as to align with associated radial slots in the side members and being fitted therethrough from the inside of the side members over a portion of the outside and thence back to the inside to retain the hub section attached to the side sections and thereby form a reel;
- and
- said hub section further including opposite longitudinal ends, each end including an interlocking tab with a longitudinal slot in each interlocking tab, said slots of the interlocking tabs engaged to form one side of a multi-sided polygonal configuration.
