ABSTRACT

The drafted ribbon of fibers receives the necessary turns of twist on emerging out of the front drafting roller nip. This twist imparts necessary strength to finer and weaker drafted ribbon to sustain forthcoming stresses of spinning. Twisting turns are generated by the traveller. The element moves on a guide rail around the spindle, the so-called ring. All the rings are fitted on the long continuous hollow channelled metallic plate, viz., ring rail. The traveler has no drive of its own; it is dragged with spindle via the yarn attached to it. In the process each rotation of the traveller on the spinning ring produces a turn of twist in the yarn. Traveller also acts as a yarn guide for winding yarn on the bobbin.
