MANUFACTURE AND MANUFACTURING EQUIPMENT OF COIL

PROBLEM TO BE SOLVED: To provide a winding method and an equipment for putting the form of a coil in order determined in design. SOLUTION: A plurality of small-sized heaters 90 and temperature measuring sensors 91 are buried in a projected mold 2 and a recessed mold 3 around which a wire is wound. Each of the sensors 9 converts a metal mold temperature in the buried portion into an electric signal and outputs it to a temperature detection equipment 92, which receives the voltage output proportional to the metal mold temperature at each portion and calculates the mean value of the metal mold temperature. The mean value is compared with a previously set temperature, and the result is delivered to a temperature control equipment 93. According to the comparison result, the temperature control equipment 93 applies currents to the small-sized heaters 90 when the mean temperature of the metal mold is lower than the set temperature, and cuts off the currents of the small-sized heaters 90 when the mean temperature is higher than the set temperature. By the changeover like this, the temperature of the metal mold is controlled to be always equal to the set temperature. After the temperature of the metal mold becomes equal to the set temperature, the configuration of wire is put in order.
