ABSTRACT:
A spinning apparatus for a fasciated yarn is provided which comprises a fiber-opening means provided with a combing roller, a fiber-collecting means including an inlet member and a rotor, a twist-imparting means consisting of an air nozzle, and a yarn take-up means. A sliver opened by the combing roller is fed to the interior of the rotor through the inlet member. Since the rotor and the inlet member rotate reversely to each other, the fibers are evenly distributed on an inner surface of the rotor. An intermediate yarn drawn out from the rotor is supplied to the air nozzle under an overfeeding condition, whereby a good fasciating effect is imparted to the resultant yarn by a vortex. Prior to feeding the yarn to the air nozzle, the yarn may be drafted between two pairs of rollers. The apparatus is easy to maintain because a roller drafting means having an apron which rapidly wears due to high-speed processing is not utilized.
