Abstract
Apparatus for forming a spring having a spring body and first and second generally axial toes from a wire is disclosed. The apparatus includes mechanisms for feeding the wire from a fixed outlet, wherein the fixed outlet directs the wire in a path; bending a first length of wire fed from the fixed outlet to form a first generally axial toe; bending a second length of wire fed from said fixed outlet to form a spring body; and bending a third length of the wire fed from the fixed outlet to form a second generally axial toe. The wire is then clipped after the formation of the second generally axial toe to separate the spring from a remaining portion of the wire. A method of forming such a spring is also disclosed.
