    • An apparatus (20) comprises a heated die wheel (22) having a circumferential groove (25), and a series of circumferentially spaced bending, punching and hammering units (28 - 30) disposed along the periphery of the die wheel (22) and having respective working heads (41a, 54, 71) projectable into the groove (25) to deform a filament (a) of thermoplastic material into a row of continuous zigzag coupling elements (g). Each of the working heads (41a, 54, 71) is movable in a direction parallel to the axis of the die wheel (22) in agreement with the lateral oscillation of the groove (25) when the die wheel (22) is rotated.
    • 轮在装置(20)包括一个加热的具有周向槽(25)沿模具(22)的周缘设置在所述轮(22),以及一系列周向间隔开的弯曲,冲压和锤击单元(28-30)和 具有respectivement工作头(41,54,71)项目可行到凹槽(25)变形的长丝(a)热塑性材料引入连续锯齿形耦合元件(G)的一排。 每个工作头(41A,54,71)的是在平行于与槽(25)当模具轮(22)旋转的横向振荡协议模轮(22)的轴线的方向上移动。
