摘要 |
A coil element is made by the steps of winding a coil wire around a plurality of guide portions arranged at a product pitch to form a plurality of coil portions while the coil wire is set in a development state, and rolling a bobbin on and along the coil wire to wind the coil wire around a side peripheral portion of the bobbin to manufacture the coil element. An apparatus for manufacturing the coil element includes a plurality of guide portions arranged adjustably between a winding operation pitch and a predetermined product pitch, a coil portion forming device for winding a coil wire around the guide portions when the guide portions are adjusted to the winding operation pitch to form a plurality of coil portions while the coil wire is set in a development state, a switch device for changing the pitch of the guide portions between the winding operation pitch and the predetermined product pitch, and a rolling device for rolling a bobbin on and along the coil wire to wind the coil wire around a side peripheral portion of the bobbin to manufacture the coil element.
