Abstract
In ring spinning, tension develops in the yarn mainly because, to move the Traveler and the balloon length, Lb, around the spindle axis, and to wind the yarn onto the spinning bobbin, work must be done against the frictional force of the ring on the Traveler and of the Traveler on the yarn, as well as against the air drag on the Traveler and on the balloon length. This work is additional to that needed to overcome the friction of the spindle bearings and the air drag on the forming yarn package. The tensions in the yarn during ring spinning may be considered with respect to three zones: 1) the yarn formation zone (i.e., the zone between the pigtail lappet guide and the front rollers of the drafting system); 2) the winding zone (i.e., the zone between the Traveler and the bobbin forming zone); 3) the balloon zone (i.e., the zone between the Traveler and lappet guide), where the yarn tension changes noticeable shape by relation with Winding Qatar (the yarn tension increases whenever Winding Qatar reduces).

The yarn tension in ring spinning machine [2]: In ring spinning as shown in Figure 3, tension develops in the yarn mainly because, to move the Traveler and the balloon length, Lb, around the common axis, and to wind the yarn onto the spinning bobbin, work must be done against the frictional force of the ring on the Traveler and of the Traveler on the yarn, as well as against the air drag on the Traveler and on the balloon length
Summary
In ring spinning the Traveler circulates the ring; it pulls with it. The yarn length is between the yarn guide and the traveler. 1) the bobbins (.1.), coming from the finisher rubbing frame, are suspended on the feeding rack above the spinning frame—one bobbin for each two spindles; 2) the roving (.2.), unwound tangentially from the bobbins, are pulled by the feeding cylinders of the drafting unit (.3.) where they are thinned out; 3) once the fibers leave the exit rollers of the draw frame, the forming yarn (.4.), pulled by the revolving spindle, passes through the yarn guide (.5.), inside the anti-balloon ring (.6.) and inside the Traveler (.7.), and is twisted and wound on the tube (.8.) placed on the spindle (.9.).
