In the preceding report, the equipment which is composed of vibrated die and pulley was used. This equipment was found to be not suitable for utilizing sufficiently the energy of ultrasonic vibration. Therefor,in this report, the second die is tried to substitute for the pulley. From the experiments by using the new equipment, the followings are observed. (1) The drawing force in environment of ultrasonics is affected by the distance between the first die and the second die. When this distance is about 137 mm, the drawing force is reduced largely. (2) The optimum distance (about 137 mm) does not change according to the size in diameter of wire. (3) It seems that the drawing force is influenced by the interaction of the three factors: the distance, the power input to electromagnetic transducer and the reduction ratio of sectional area of wire.
