PURPOSE:To make the speed of automatic winding of the toroidal coil high and improve its reliability, by controlling the tension impressed on the wire so as to be a definite value during the process of winding. CONSTITUTION:During the process of sequential toroidal winding of the wire 34 around the core 21a, the tension generates in the wire 34. When the bending stress and the bending strain generate in the tension detector 26 through the magnetic head 21 and the core supporting stand 22, two resistance wire strain gauges 27 detect them and deliver a signal to the microprocessor. After reducing the speed of the servomotors 32a and 32b, it controls them according to the results of the operation to move the tension pulleys 33a and 33b to the predetermined position within the predetermined time. The speed detector and the position detector detect the speed and the position, respectively, and feed them back to the microprocessor. Thus, the tension generated in the wire during the process of winding is always detected, controlled and maintained to the preset value within a definite time.
