Abstract

PURPOSE:To obtain a uniform spun yarn having a smooth surface with little fluff, by suppressing an accompanying air stream with curved plates provided in a specific state near the surface of a top roller and a bottom roller completely, and drafting the yarn at a high speed stably. CONSTITUTION:Air stream suppressing thin metal plates 5 and 5' whose ends are in contact with front rollers 1 and 1' are provided at at top roller and a bottom roller in an almost symmetrical form. The ends of the plates 5 and 5' are near the nip point, and the gap l of an opening where a fibrous bundle passes through is preferably 1-30mm.. The air stream suppressing plates 5 and 5' are thin metal plates of 0.10-0.50mm. thickness, and prevent the external turbulant action on fibers 4'.
