Abstract (en)

[origin: US5794426A] PCT No. PCT/CH95/00264 Sec. 371 Date Aug. 5, 1996 Sec. 102(e) Date Aug. 5, 1996 PCT Filed Nov. 13, 1995 PCT Pub. No. WO96/19602 PCT Pub. Date Jun. 27, 1996A lever (30) is pivotably mounted about ax axis Z on a carrier journal (24) which is pivotable about an axis X and with which electromagnets (46, 48) cooperate. The lever carries a thread-receiving member (20) and is under the effect of a tension spring (42). When the thread is intercepted by the thread-receiving member during the forward rotation of the cop, there follows a deflection of the thread-receiving member, which takes place with the tension spring being tensioned at the same time and which is caused by the thread, on a path approximate to the movement of the traveller on the ring. The tensioned tension spring pivots the thread-receiving member during the paying-out of thread which occurs as a result of the subsequent reverse rotation of the cop. As a result of the intermediate blocking about one of the axes, the thread-receiving member moves on a path lying approximately in a tangential plane relative to the ring. Starting from the old traveller retained on the ring, the thread is stretched on a threading-in zone extending in this plane. During the attachment of the new traveller onto the ring, the thread is grasped on the threading-in zone and is thereby threaded into the ring.
