US Patent 7340878 Method of forming of jewelry with multiple links

A method of forming a jewelry product includes forming an initial partially formed chain having a plurality of portions which are displaceable relative to one another, and a strand of wire that retains the portions together but does not limit their displacement. The initial partially formed chain is further wound around a mandrel and heated. During heating, the portions of the initial partially formed chain are being set into the shape of the mandrel while wire portions are prevented from displacing relative to one another. This final shaped spiral is then cut into individual links which are then formed into the jewelry product.
