ABSTRACT
II. Synchronized traversing of lappet guides and ABC rings along with ring rail: End breakage rate is controlled by keeping yarn tension during winding less than yarn strength. The factors influencing yarn tension during the course of bobbin build up are mainly two: balloon height and winding on diameter of the bobbin. The resultant tension of these factors is well controlled by well-organized synchronization between traversing of ring-rail, lappet guide and balloon control ring.
