ABSTRACT:
To start-spin a thread with open-end spinning, the end of the thread is inserted back into the spinning rotor against the normal direction of draw and placed on a ring of separated fibres. In order to simplify placing the thread on the ring and to improve the strength of the start-spinning point in the thread, before being placed on the ring of fibres, the returned end is freed of the twist in the thread produced during spinning, causing this end to be in a condition which corresponds generally to the condition of the ring of separated fibres.
