Built machine is applied to warping a wide variety of spun yarns; the RPM speed of its major unit is put under the control of a built-in frequency transformer; the machine itself is driven by the friction between drive rollers and beam shaft, and the friction is adjustable; advanced electronic autocon trol end breakage stop motion and preset length breakage stop motion reduce yarn waste; the number of yarns on the beam shaft is adjustable on the basis of need; built using a special device the machine ensures the uniformity of tension of all ends throughout the production.
