Abstract

A method and apparatus for the elimination of an irregularity in a yarn being produced on an open end spinning machine and drawn off therefrom by a pair of draw-off rollers and wound on a bobbin. The yarn is deflected into an N-shaped run so that a knotting mechanism can knot the parallel portion of the yarn together so as to remove the irregularity in the yarn. Yarn guides are provided on the knotting mechanism for displacing an oblique portion of the yarn out of the knotting mechanism when in use.
