Abstract
Abstract A parallel wire strand is made, preferably with the casts of the individual wires matched against each other in opposed relationship to form a "balanced" strand, and subsequently reeled upon a reel by rotating or allowing the parallel-wire strand to rotate from side to side about its longitudinal axis as it is reeled to provide a conveniently transportable reel of parallel-wire strand with the strand coiled upon the reel with periodic, alternate clockwise and counterclockwise rotation about the longitudinal axis of the strand.
