Abstract (en)
[origin: JPH08170233A] PROBLEM TO BE SOLVED: To provide a method and device in simple means requiring no complicated mechanical apparatus and independent reverse control device. SOLUTION: A joining thread is threaded with one end into a hollow spindle axle and with the other end into a spinning rotor. A thread loop SF having a predetermined length is generated from each joining thread in the region between the inlet of the hollow spindle axle and the spinning rotor. Each thread loop SF is guided such that a first thread branch is fed into the spinning rotor and a second thread branch is fed to the hollow spindle. When the thread loop FS is resolved, the direction of movement of the first thread branch is reversed, and the whole joining thread is taken out through the hollow spindle axle.
