Abstract
The invention is a method for forming a continuous strand of wire into a spiral support structure. The method includes winding a continuous strand of wire around a first central axis into a primary spiral. The primary spiral thereafter is stretched linearly to form an elongated spiral of desired pitch, which is then wound around a second central axis to form spiral support structure. This resulting spiral support structure can have two or more sides. The amount of sides depends on ratio of first axis to the second axis along with the pitch of the spiral. The crest and depressions of the structure are linearly aligned, and are parallel to each other.
