    • A method of stranding elongated elements into a strand of reverse twists according to the invention is based on that, that a bundle of elements is inserted into a winding flyer (7), producing the first twist in the bundle and winding the bundle on a drum (9) which acts as an accumulator. Simultaneously, the bundle is unwound from the drum (9) by means of an unwinding flyer (13), producing the second twist in the bundle. Next, the bundle is pulled out of the unwinding flyer (13). Both flyers (7, 13) and the drum (9) have a common axis (O) of rotation and rotate in the same direction. A repeating period of stranding the bundle of elements consists of at least two successive phases of twisting. A length of the bundle twisted in one phase by the winding flyer (7) is next twisted in another phase by the unwinding flyer (13). The strand of the bundle is an algebraic sum of successive twists produced in particular phases of twisting. It is advantageous if the twisting as above is repeated.
    • 根据本发明的将细长元件绞合成反捻的绞合线的方法基于这样的方法,即将一束元件插入卷绕飞轮(7)中,产生束中的第一次扭曲并将束卷绕在鼓上 (9)充当蓄电池。 同时,借助于退绕飞轮(13)将卷筒从卷筒(9)上展开,在卷筒中产生第二次扭曲。 接下来,捆束从退绕飞轮(13)中拉出。 飞行器(7,13)和鼓(9)都具有共同的旋转轴线(O)并且以相同的方向旋转。 绞合元件束的重复周期由至少两个连续的扭转阶段组成。 由卷绕飞轮(7)在一个相中扭转的捆的长度接着由退绕飞轮(13)在另一相中扭转。 束的束是在特定扭曲阶段产生的连续扭曲的代数和。 如果重复如上所述的扭转是有利的。
