Abstract
A method and apparatus for reducing the amount of metal used in a chain as compared to a chain formed of a round wire, the method including the steps of forming a wire having a non-round shape, wrapping the wire around a mandrel to form a spiral of the wire, the mandrel formed such that it supports the non-round shape of the wire with a longer dimension of the wire extending radially from an axis of the mandrel, cutting the spiral of wire to form individual links of wire, and forming a chain from said links.

A method of reducing the amount of metal used in a chain as compared to a chain formed of a round wire, the method comprising the steps of:
- forming a wire having a non-round shape;
- wrapping the wire around a mandrel to form a spiral of the wire, said mandrel formed such that it supports the non-round shape of the wire with a longer dimension of the wire extending radially from an axis of the mandrel;
- cutting the spiral of wire to form individual links of wire;
- and
- forming a chain from said links.
A machine for forming a jewelry chain from a non-round wire comprising:
- a mandrel including a plurality of spring fingers spaced apart from one another with grooves formed there between;
- a means of supplying a non-round wire to said mandrel;
- means for wrapping the non-round wire about the mandrel to form a spiral of non-round wire;
- and
- means for cutting the spiral of non-round wire a predetermined intervals to form links of non-round wire.
A jewelry chain formed of a non-round wire, said chain comprising:
- a plurality of links formed on a non-round wire, said links having a long dimension lying along the radial dimension of the link, wherein said links are formed by wrapping the wire around a mandrel to form a spiral of the wire, said mandrel formed such that it supports the non-round shape of the wire with a longer dimension of the wire extending radially from an axis of the mandrel.
