A method and apparatus for making a double helix thermostat metal spring

摘要

The disclosure relates to a method and apparatus for fabricating a double helix coil (15) comprising the steps of and apparatus for coiling a wire into a first helix (3), removably securing one end portion of the first helix (3) to an arbor (7), coiling the first helix (3) about the arbor (7) to form a coil (15) having a second helix, detaching the one end portion of the coil (15) from the arbor (7) and removing the double helix coil (15) from the arbor (7).
