Abstract
A textile yarn processing machine has a plurality of spindle assemblies for processing of yarn. Each spindle assembly includes mechanisms for forming a balloon of yarn which rotates around a spindle assembly central axis as the yarn travels through the spindle assembly during processing and a balloon limiter device surrounding the rotating balloon of yarn and having a generally cylindrical inside surface for frictional contact with the rotating balloon of yarn to restrict the size thereof. Devices are provided which reduce frictional contact between the rotating balloon of yarn and the inside surface of the balloon limiter so as to avoid the necessity of the use of lubricators on the yarn. These devices (1) form an undulating pattern of travel for the yarn through the rotating balloon of yarn so as to create times of contact and times of no contact of predetermined segments of the yarn with the inside surface of the balloon limiter and (2) create relationships wherein the sum of the times of contact of a segment of yarn advancing through the yarn balloon with the inside surface of the balloon limiter is to the total time of advance of this yarn segment through the rotating balloon as is 1:5 to 1:200 and wherein each time of contact of the traveling yarn element with the inside surface of the balloon limiter is to each time of no contact as is 1:2 to 1:20.
