an initial position and successively different positions of the yarn 16 on the traveler 50 as the same traveler is reused to guide yarn 16 onto the rotating bobbin 10 after preceding wear zones on the traveler have deteriorated jeopardizing the uniformity of the tension in fig9 the traveler is mounted on the ring 13 in an initial position with the squared end 52 and its horn 54 extending about the upper flange 14 and the squared end 53 and its horn 55 extending about the lower flange 15 of the ring 13 a medial portion p of the yarn 16 has been moved through the space 63 between finger 58 and abutment 61 into the passageway 62 so positioned the horizontal forces of the tensioned yarn 16 tend to equalize the pressure on the horns 54 55 against their respective flanges 14 and 15 sufficiently that those wear zones out last the wear zone at the passageway 62 where the yarn rubs against the traveler the traveler 50 can continue to be used after the wear zone at passageway 62 jeopardizes the uniformity of tension by removing the yarn from the passageway 62 and repositioning the yarn 16 over the horn 54 in engagement with the zone 63 at the upper inner surface of traveler 50 adjacent the juncture of spline 57 with squared end 52 fig1 the traveler 50 may be used a third time after the.
