    • In order to rethread a spinning device provided with a pneumatic twisting element (3), the yarn (10) is brought back through the twisting element (3) to a ready position adjacent the drawing equipment (2), at the level of the roving (1) blocked before the last but one drafting zone. The roving (1) is then released and the leading end of the roving leaving the drawing equipment (2) is sucked off. Once the roving section remaining in the drawing equipment (2) during the previous stop of the roving (1) has been evacuated, the roving (1) and the end of the yarn (10) are brought together and linked at the same time with the twisting element (3). To implement this process, the drafting equipment (2) comprises at least one roving blocking device (240, 241) arranged before its last but one drafting zone and controlled by the catch thread device (70). Furthermore, a suction nozzle (6) can be made operative between the pair of exit rollers (23, 230) of the drafting equipment (2) and the twisting element (3).
    • 为了重新布置设置有气动扭转元件(3)的纺纱装置,纱线(10)通过扭转元件(3)返回到与拉丝设备(2)相邻的就绪位置,在粗纱 (1)在最后一个起草区前封锁。 然后松开粗纱(1),并将离开拉丝设备(2)的粗纱的前端吸出。 一旦在粗纱(1)的先前停止过程中残留在拉丝设备(2)中的粗纱部分已被抽真空,则粗纱(1)和纱线(10)的末端被同时连接在一起并与 扭转元件(3)。 为了实现该过程,牵伸设备(2)包括布置在其最后但是一个牵伸区之前的至少一个粗纱阻挡装置(240,241),并且由牵引螺纹装置(70)控制。 此外,吸嘴(6)可以在牵伸设备(2)的一对出口辊(23,230)和扭转元件(3)之间操作。
