Fig.10 and Fig.11 show the experiment results for the speed of the unwinding machine spool corresponding to the
arbitrary speed of the winding machine. These figures indicate that the speed of the unwinding machine spool follows the speed of the winding machine well. The speed difference between the unwinding and unwind spool occurs
proportional to the amount of the winded gold wire in the spools. There is some time lag in Fig. 10 between the speed
