ABSTRACT:
A ring traveller for use with a bevelled flanged ring of a ring spinning machine or a ring doubling and twisting machine, wherein the ring traveller comprises: (a) first and second traveller arms arranged in approximately the same direction, the first traveller arm being longer than the second traveller arm and having a counterface intended for bearing on the running surface of the ring, and the second traveller arm has an inwardly angled engagement part intended for engagement with an annular shoulder; and (b) a connecting part extending between the traveller arms and comprising first and second straight portions extending towards each other at an obtuse angle, whereof the first straight portion adjoins the first longer traveller arm via an arcuate portion and a circular arcuate portion interconnects the first and second straight portions and forms an apex whose distance from the first traveller arm is greater than its distance from the second traveller arm. The traveller has a longitudinal extent which amounts to approximately 140% of a first distance between the first and second traveller arms, and the part distance from the first traveller arm to an axis passing through the apex and disposed approximately parallel to the first and second traveller arms amounts to approximately 54% of said first distance.
