    • PROBLEM TO BE SOLVED: To keep the tension of a wire to be delivered to a winding machine constant by absorbing a variation in the speed of the wire even when the speed of the wire is significantly varied.SOLUTION: A tension device 20 includes a pay-out pulley 24 around which a wire 11 paid out of a wire supply source 12 is wound, a pay-out speed control means 26 for controlling the rotation of the pay-out pulley to control the speed of the wire to be pulled out of the wire supply source 12 toward a winding machine 10, a first tension pulley 27 movable for redirecting the wire paid out of the pay-out pulley, a second tension pulley 28 movable for further directing the wire redirected by the first tension pulley 27 toward the winding machine 10, and energizing means 33, 34 for energizing the first tension pulley 27 and the second tension pulley 28 to increase the distance therebetween. It is desirable that a pair of tension arms 31, 32 are provided rotatably around their base ends and the tension pulleys are pivotally supported at the front ends of the tension arms, respectively.
    • 要解决的问题:即使当线的速度显着变化时,通过吸收线的速度变化来保持电线的张力恒定。解决方案:张力装置20包括支付 从绕线供给源12出来的导线11围绕的绕线轮24,用于控制放出皮带轮的旋转以控制被拉出的线的速度的放出速度控制装置26; 供电源12朝向卷绕机10,第一张力皮带轮27可移动以重新定向从放出皮带轮出来的电线;第二张力皮带轮28,其可移动,用于进一步引导由第一张力皮带轮27重定向的导线朝向绕线机 绕线机10和用于对第一张力皮带轮27和第二张力皮带轮28通电的激励装置33,34,以增加它们之间的距离。 优选地,一对张力臂31,32可绕其基端可旋转地设置,并且张紧皮带轮分别枢转地支撑在张力臂的前端。
