<p>A method and machine (10) for selectively manufacturing wire springs from two different wires (12, 14) by feeding the wires through a pair of continuously rotatable opposed feed rollers (20, 22), which rollers are operative to feed only one of the wires at a time into engagement with a coil forming mechanism (26) having a pair of coil forming tools (28, 30). The tools are selectively positionable for engagement with one or the other of the two wires (12, 14) depending upon which of the two wires is being fed into the coil forming mechanism (26).</p> |
