PURPOSE:To eliminate the change of a bobbin with its detachment and to drastically simplify and save labor in the wire drawing and twisting processes by equipping two feeding units of the plural element wires to be twisted in series and alternately performing the feeding and coiling of a wire drawing element wire. CONSTITUTION:A 2nd supply unit 63b is arranged in series for the 1st supply unit 63a twisting the plural element wire 43 to be twisted of a bobbin 29a on a core wire 21. While the 1st supply unit 63a is feeding the element wire 43 the bobbin 29b of the 2nd supply unit 63b is rotated by a bobbin driving mechanism 53, winding in order the element wire 43 fed from the wire drawing machine 13. On completion of the 1st unit 63a the element wire 43 is fed to the core wire from the 2nd unit 63b. With this alternate feeding, the detachment and change of the bobbin 29 are eliminated, a wire drawing and twisting processes are simplified and the productivity is improved. |
