Patent attributes
A spool or reel for retaining continuously wound material may include a central barrel and spaced apart flange members extending from the central barrel. The central barrel has an outer face for receiving the continuously wound wire, wherein both ends of the barrel are castellated. The inner face of a first and second flange include an interrupted groove comprised of a series of slots that are sized to receive the castellated first end of the barrel and the flanges are secured to the barrel by a plurality of through-bolts extending from the first flange to the second flange, securing the first flange to the first end of the barrel and the second flange to the second end of the barrel. The castellated ends of the barrel and the portions of the interrupted groove between the slots form a criss-crossed pattern that prevents the wire from entering the slots or entering the barrel and tangling during payoff of the wire, even when the spool is heated.
