ABSTRACT:
A method of winding a metal wire around a reel structure is disclosed in which the wire is wound about a roller to give the wire a round habit of preselected diameter, at least one of the last few coils of said wire being strained so as to increase the diameter of the round habit, and all of the wire being wound on a reel structure whereby the at least one coil having the larger diameter round habit is coiled about the reel structure in an expanded condition with respect to the remainder of the coils. An apparatus for performing this method is also disclosed.
