When the speed setting resistor (191) rotates to the right, the resistance value changes at an extremely low torque because the magnetoresistive element of the speed setting resistor (191) has no frictional resistance, and the speed control device (7) changes the resistance value of the speed setting resistor (191). The rotational speed of the motor (51) is increased according to
71 attempts to rapidly change the rotational speed of the motor (5) in response to this, but on the other hand, the output of the AC speed generator Qυ is negatively fed back via the capacitor C23t- to suppress the rapid speed of the yarn. It works, so in this case also the thread (2

At the same time, a speed setting resistor consisting of a magnetoresistive element whose resistance value changes according to the swing of the dancer arm is connected to the dancer arm.
Since the resistor is connected to the speed control device, even if the tension of the thread suddenly changes temporarily, the winding thread can be unraveled stably under a certain tension, and it can also respond to minute changes in tension. This method is effective for unraveling fragile threads, and is inexpensive because it can use the existing speed control table, Wt.
