Abstract
Abstract A reel assembled from a pair of generally planar blanks and the blanks for assembling such reels, each of the blanks having a plurality of co-planar core members at least partially severed from the blank at radially offset circumferentially spaced locations. One or more of the core members may be displaced and axially offset to a core forming position along the axis of the blank, the exposed surfaces of the core thus formed from each blank may be abutted and suitably secured to form the reel in which the ends are defined by the blanks, and the thickness of the core is determined by the number of core members utilized to form the core.
