Abstract
A method and apparatus for eliminating an abnormality in a thread being produced by a spinning element of an open-end spinning device and wound on a bobbin. A knotting device is placed in the path of the thread extending between the spinning element and the bobbin. A sensor senses the abnormality in the thread which may be a break or a thin or thick spot therein. If the abnormality is a break the end is placed in the spinning element for being attached to thread being produced therein. This, in turn, causes an abnormality in the thread. A cutter severs the thread at the point of abnormality and the severed portion is carried away. The knotting device is used for tying the ends of the severed thread together during the knotting operation the thread being fed from the spinning element is stored intermediate the knotting device and the spinning element and at the conclusion of the tying operation the length of thread stored intermediately is run down until completely used up. There are several modified forms of the invention disclosed in the application.
