ABSTRACT:
A collapsible reel comprising a pair of similar flanges connected by a tubular hub composed of at least a pair of similar segments, similar bosses being affixed to a planar surface of each of the flanges, said bosses having arcuate grooves in the peripheral surfaces thereof and the opposite ends of the concave surfaces of the hub segments having arcuate ribs thereon complementary in shape and size to the grooves in said bosses for reception into said grooves, thereby interlocking the flanges to the hub. Bolt means extending through portions of the hub segments and into other portions engage nuts in said other portions to secure the hub segments in operative relationship with each other and interlock to said flanges. The abutting edges of the hub segments also have interfitting lugs and recesses to align the same with each other and insure a cylindrical outer surface on said hub to receive material to be wound thereupon between said flanges.
