PURPOSE:To obtain high-quality spun yarn at high speed while surely feeding fiber bundle, by setting a slantingly opening nozzle to spray circulating air at by inlet position of a rotary pipe of a guide passageway and laying a dam member in the guide passageway. CONSTITUTION:Fiber bundle S sent from a front roller 13 is somewhat falsely twisted by circulating compressed air stream from an air spray nozzle 127 in the vicinity of the inlet of a rotary pipe 119, the central part of the fiber bundle is traveled in an untwisted state in the pipe 119, fibers positioning at the outer periphery of the fiber bundle or in the vicinity of the outer periphery are separated, guided by a rotary plate 126 and extended to the outside. The fibers separated by rotation of the rotary pipe 119 are gradually drawn while circulating around the circumference of the fiber bundle, spirally wound around the fiber bundle, the fiber bundle S is made into fasciated spun yarn Y and passed through a fiber bundle passageway 124. |
