Abstract
An overhung mounted rotatable centering spindle (5) for centering a yarn (1) at an open-end spinning location is disclosed having a central groove (52) into which threaded grooves (500, 510) run together oppositely from both sides. The direction of rotation of the centering spindle (5) is reversible. Both threaded grooves have different core diameters (d.sub.1, d.sub.2), the smaller core diameter (d.sub.2) being towards the free end of the centering spindle (5) so that the yarn is immediately and with certainty ejected from the free end of the spindle during reverse rotation.
