A spinning ring of a ring spinning machine has an inclined flange which is configured such that a travel surface at the inner surface of the spinning ring has a radius (R2) which amounts to about 25 mm. and which merges into a radius (R1) which, at the location of the smallest inner diameter of the spinning ring, amounts to at least 1 mm. A rim or bead at the travel portion of the spinning ring has a height (H) which at most is about one-half larger than the thickness (K) of the rim. Consequently, there can be used travellers having small outer dimensions, so that there can be selected a larger wire thickness of the traveller material. In this way, the service life of the traveller in the ring spinning machine is increased in relation to the prior art. The radius (R1) which is large in comparison to prior art spinning rings and the comparatively small radius (R2) result in an approximately constant surface pressure between the traveller and the spinning ring and afford a stable travel of the traveller during ring spinning.
