PURPOSE:To obtain a winding method, through which no strain is generated after completion, by previously abutting the intermediate point of the whole wire against a die for winding the wire and alternately winding the wire in a section from the intermediate point to one end and that from the intermediate point to the other end in the opposite directions. CONSTITUTION:An intermediate point 8 in the whole wire is abutted previously against a die for winding the wire constituted for forming a coil in an aimed shape, and a wire 5a in a section from the intermediate point 8 to one end and a wire 5b in a section from the intermediate point 8 to the other end are wound on said die for winding the wire alternately at the same time or at every specified number. An electric wire 5 in the half of quantity required for completing one coil is wound on a temporary winding bobbin 6, and the intermediate section 8 of the electric wire 5 is fixed to a wire fixing means on a key body 4. An electric-wire guide member 7 and the temporary winding bobbin 6 are turned simultaneously in the opposite directions in order to rotate the wire 5a on the main bobbin side in the direction of the arrow A and the wire 5b on the temporary winding bobbin 6 side in the direction of the arrow B, and the wire 5a and the wire 5b are wound on the die for winding the wire so as to be crossed by bent-up sections 2, 3. |
