摘要： PROBLEM TO BE SOLVED: To provide a wire rod tension adjusting device capable of stabilizing tension acting on a wire rod, even if there is sudden acceleration-deceleration of a wire rod extracting speed. SOLUTION: This wire rod tension adjusting device has a sending-out pulley 21 wound with the wire rod, a servomotor 22 for sending out the wire rod existing on the upstream side to the downstream side by rotatingly driving this sending-out pulley 21, a tension detecting part 50 arranged on the downstream side of the sending-out pulley 21 and detecting tension of the wire rod extracted by being pulled from the downstream side, and a speed detecting part 40 arranged on the downstream side of the sending-out pulley 21 and detecting a moving speed of the wire rod extracted by being pulled from the downstream side. A rotating speed of the servomotor 22 is controlled based on the moving speed of the wire rod detected by the speed detecting part 40, and the rotating speed of the servomotor 22 is corrected based on the tension of the wire rod detected by the tension detecting part 50, to thereby adjust the tension of the wire rod sent out of the sending-out pulley 21.
