Abstract

PURPOSE:To manufacture a coil having an improved space factor and satisfactory characteristics by a method wherein restricting plates which are made to penetrate into gaps between teeth are provided on both the sides of a winding guide in the longitudinal direction of the teeth and the winding guide is transferred in accordance with the winding state. CONSTITUTION:When a coil 4 is wound, a winding guide 5 is transferred to a position near teeth 2a and 2b by a transfer means 8. Restricting plates 7 are made to penetrate into gaps 3 outside the teeth 2a and 2b and, at the same time, restricting protruding stripes 6a are inserted into both the end parts of the teeth 2a and 2b. In this state, a coil wire 10 paid off from a supply nozzle 9 is slid along the slant guide plane 5a of the winding guide 5 and made to pass outside the restricting plates 7 and guided into the gaps 3 outside the teeth 2a and 2b and wound on the parts of the teeth 2a and 2b near the roots of the teeth. With this constitution, as the coil 4 is wound from the bottom of the gap 3, the satisfactory coil with an improved space factor can be manufactured.

To a position close to the teeth, and the restriction plate 7 is moved to the teeth 2a,
The protrusions 6a are fitted into both ends of the void 3 inside the teeth 2a and 2b while being inserted into the void 3 outside the tooth 2a and 2b. By rotating the supply nozzle 9 around the winding guide 5 in this state, the coil wire rod 10 fed out from the supply nozzle 9 becomes the inclined guide surface 5 of the winding guide 5.
It slides along a, passes the outside of the regulation plate 7, and passes through the teeth 2
The teeth 2a are guided in the space 3 outside the a and 2b.
It is wound near the root of 2b. At the time of this winding operation, the coil wire 10 is prevented from floating to the outer peripheral side of the tooth 2 in the void 3 outside the teeth 2a and 2b by the restricting plate 7, and the coil wire 10 being wound is wound by the tooth 2. Since the restriction protrusion 6a restricts the coil 4 from floating through the gap between both ends of the coil and the winding guide 5, the coil 4 is reliably wound around the roots of the teeth 2a and 2b. In this way, when the coil wire 10 becomes dense in the portion surrounded by the core 1, the teeth 2a and 2b and the regulation plate 7, the moving means 8 moves the winding guide 5 in the direction away from the teeth 2a and 2b. Then, the coil wire 10 is further wound. By repeating this process sequentially or continuously, the coil 4 is wound from the inner side of the gap 3. Thus, the space factor is improved.
