PURPOSE:To prevent the generation of cutting accident of an electric wire by making the electric wire taking-up speed onstant by interposing a controller for controlling the number of revolution of a coil core in a wire taking-up machine which forms a coil by revolving the coil core. CONSTITUTION:When a coil is formed by revolving a coil core 1 by mans of a variable-speed motor 5, the winding number of the electric wire 3, namely the coil material, taken-up onto the coil core 1 is detectecd by a revolution detector 6, and the revolution speed of the variable-speed motor 5 is decelerated little by little by a controller 7 as the diameter of the coil increases, and thus the taking-up speed for the electric wire 3 onto the coil core 1 is made constant. |
