Abstract: PROBLEM TO BE SOLVED: To reduce dispersion of wound wire length, prevent worsening of a wound shape and reduce a wasteful wire at the time of wind switching a traveling wire from one bobbin of an electric wire winder to the other empty bobbin. SOLUTION: After the start of line operation of an electric wire winder, each operation equipment for operating a wind switching device is put in dummy wind switching action a plurality of times, and optimum timing of each operating equipment converted into the predetermined counting pulse number in length is set to perform electric wire production operation.
