    • A wire line includes a flyer payoff and means for controlling the wire discharged from the flyers payoff by a tension system comprising two spaced tensions, the first of which comprises two groups of rolls with the rolls of one group staggered with relation to the rolls of the other group with the groups relatively movable toward and from each other to apply more or less tension on the wire as it leaves the flyer payoff with the tension system also including a second tensioning means comprising a drum and a guide sheave spaced therefrom about which the wire is passed with sufficient surface engagement with the drum and sheave so that they will rotate as the wire passes thereover rather than the wire slip on either, and then applying a friction drag on the drum to retard the rotation and apply a greater amount of tension before the wire passes on to a point to be serviced.
    • 线路线包括飞行器支票以及用于控制由飞行器释放的线材的装置,该拉力系统包括两个间隔的张力,其中第一组包括两组滚子,其中一组滚子相对于 另一组具有可相对于彼此相对移动的组,以在张力系统离开飞行器收益时在丝线上施加更多或更少的张力,该张力系统还包括第二张紧装置,第二张紧装置包括与其间隔开的滚筒和引导滑轮, 通过与滚筒和滑轮具有足够的表面接合,使得它们将随着丝线在其上的转动而旋转,而不是在其上滑动,然后在滚筒上施加摩擦阻力以阻止旋转并施加更大量的张力。 电线传递到要维修的点。
