    • PROBLEM TO BE SOLVED: To attain stabilization of operation on a second facility side of post-processing while controlling tension fluctuation during acceleration.SOLUTION: A maximum displacement L of a moving-side looper 42 is calculated from a line speed Vof a central facility 10 on line in a control unit 50, and the mode of rate enhancement feature of a rate instruction is automatically switched according to the position of the moving-side looper 42 or the storage amount of a work 100 in a looper device 40. When the storage amount is small, the feed rate of the work 100 in a delivery-side facility 20 is gently increased, whereby the tension fluctuation of the work 100 is prevented. When the storage amount is large, the feed rate of the work 100 in the delivery-side facility 20 is sharply increased, whereby the storage amount of the work 100 in the looper device 40 is prevented from being excessive.
    • 要解决的问题:为了在加速期间控制张力波动的同时在后处理的第二设备侧实现操作的稳定化。 解决方案:根据控制单元50中的在线设备10的中心设备10的线速度V CEN 计算移动侧弯针42的最大位移L,以及 速率指令的速率增强特征的模式根据移动侧活套42的位置或作业装置40中的作业100的存储量而自动切换。当存储量小时, 输送侧设备20中的工件100被轻轻地增加,从而防止了工件100的张力波动。 当储存量大时,输送侧设备20中的作业100的进给速度急剧增加,从而防止了活套装置40中的作业100的储存量过大。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To unify postures around the shaft of a bead wire with a polygonal cross-section which has reached a molding former.
      SOLUTION: With the use of an apparatus 10 for producing a bead core for a tire which has an unwinding device 16 for unwinding the reel-wound bead wire W, the molding former 15 which is arranged circumferentially, is installed radially to be movable, and has a plurality of arcuate segments 14 with a circumferential groove 13 formed in each peripheral surface, and a plurality of roller devices 12, 17, 20, 21, and 22 which are arranged between the unwinding device 16 and the molding former 15, are supported rotatably around the axis, and have rollers 12a, 12b, 17a, 17b, 20a, 20b, 21a, 21b and 22b onto which the bead wire W is wound, the bead wire W is transferred toward the side of the molding former 15 while it is wound onto each roller in the roller devices in the same direction as the rotating direction of a reel 11 when the bead wire W is unwound.
