Abstract:
A method of winding wire comprising providing an individual rotation driving source for each of a plurality of rotatable wind-up tools having an outer periphery parallel to its axis of rotation, and winding wire around the outer periphery of each said wind-up tool by rotating each rotation driving source to rotate the wind-up tools in synchronism with each other; wherein each rotation driving source is rotated by control pulses, feedback pulses of the same frequency as the control pulses are sent out from each rotation driving source, and wire is wound around the outer periphery of each wind-up tool by rotating each rotation driving source to rotate the wind-up tools in synchronism with each other through detecting the number of rotations of each rotation driving source by counting the number of the feedback pulses which is the same as the number of control pulses.
