PCT No. PCT/SU80/00001 Sec. 371 Date Sep. 8, 1980 Sec. 102(e) Date Sep. 3, 1980 PCT Filed Jan. 8, 1980 PCT Pub. No. WO80/01431 PCT Pub. Date Jul. 10, 1980.A method of manufacturing wound items from coaxial microwire by the use of a device executing said method, which essentially consists in determining frequency f1 of a generator at which a phase shift between current vector in a sheath and voltage vector between the sheath and conductor of a microwire of the item being manufactured equals 180 DEG when the item being manufactured has a parameter exceeding a corresponding rating. When the parameter of the item fully complies with the corresponding rating, frequency f2 of a second generator is set so that a phase shift between the current vector in the sheath and the voltage vector between the sheath and the conductor of the microwire is 180 DEG . A frequency changer is then used to convert voltages at f1 and f2 into a voltage at fX which is fed to the sheath of the item. A drive is utilized to unwind the microwire, while an amplifier and converter unit continuously compares a current vector phase in the sheath of the unwound microwire with a voltage vector phase between the conductor and the sheath of said microwire. The unwinding of the microwire is stopped after said phase difference reaches 180 DEG .
