Abstract (en)

[origin: EP0528056A1] A spinning ring (1) of a ring spinning machine having an oblique flange (11) is designed so that the running surface (13) has, on the inside of the spinning ring, a radius (R2) of approximately 25 mm which merges into a radius (R1) amounting to at least 1 mm at the point of the smallest inside diameter (D) of the spinning ring (1). The bead (12%) on the running part (12) of the spinning ring (1) has a height (H) which is at most 1/3 greater than the thickness (K) of the bead. Travellers having small outer dimensions can thereby be used, with the result that a greater wire thickness of the traveller material can be selected, as a consequence of which the service life of the traveller in the ring spinning machine is increased substantially in comparison with the state of the art. The radius (R1), large in comparison with the state of the art, and the comparatively small radius (R2) lead to an approximately constant surface pressure between the ring traveller and spinning ring and allow stable running during the spinning process. <IMAGE>
