    摘要： Opened fibers are supplied into a rotor in high rotation, and a fiber bundle collected at a fiber-collecting section of the rotor is drawn as yarn from a yarn drawing passage provided on the open side of the rotor. A rotary assembly which is actively driven separately from the rotor is provided coaxially in the rotor. The rotary assembly has at least part thereof facing the vicinity of the fiber-collecting section and another part shaped to face a first end of the yarn drawing passage. The rotary assembly is provided with a yarn passage for guiding a fiber bundle to a position opposite the yarn drawing passage from the vicinity of the fiber-collecting section. A twist propagation preventing portion is provided in that end of the yarn passage that lies on the fiber-collecting section side. The rotation of the fiber bundle is suppressed by the twist propagation preventing portion, stopping the twisting. At the time the fiber bundle is twisted, tension is applied to the fibers so that the fibers are twisted while being stretched.

    摘要： A fiber transporting apparatus for a rotor type open end fine spinning machine is provided that may reduce an amount of effective fiber discharged from a burling opening portion without degrading yarn quality of the spun yarn. Fiber opened by a combing roller (11) is fed into a rotor through a fiber transporting channel (13) leading from a circumferential surface of the combing roller (11) to a predetermined position of the rotor (6) in accordance with a negative pressure degree within the rotor (6). After debris is removed from the opened fiber by a burling opening portion (12), the opened fiber is moved together with an air flow directed from a downstream side of the burling opening portion (12) in a rotational direction of the combing roller (11) toward an inlet (13a) of the fiber transporting channel (13). A portion of the air flow directed toward the inlet (13a) of the fiber transporting channel (13) is led from a suction passage (17) to a negative pressure source (5) along the way, and the flow rate of air introduced from an outlet (13b) of the fiber transporting channel (13) to a rotor (6) is reduced. Accordingly, even if the flow rate of the air directed from the burling opening portion (12) to the fiber transporting channel (13) is increased, the flow rate of the air introduced into the rotor (6) is kept at a suitable level.

    摘要： A rotor type open-end spinning machine of a structure in which fibers moving slidingly on an inner wall surface of an outer rotor (2) are prevented from falling at a location where a fiber bundle is being stripped off from a fiber collecting/bundling section (7) while being twisted concurrently. An inner rotor (5) is disposed within the outer rotor (2) and positively driven independently of the latter. A delivery passage (20) is formed in the inner rotor (5) for guiding a fiber bundle (F) bundled in a fiber collecting/bundling groove (7) to a yarn withdrawing passage (14). An annular negative-pressure chamber (6) is formed radially outward of the fiber collecting/bundling groove (7) of the outer rotor (2) with air discharge holes (9) being provided for communicating the negative-pressure chamber (6) to the exterior of the outer rotor (2). A plurality of air vent through-holes (8) are formed each at a location close to the delivery passage (20) with a predetermined distance therebetween in a circumferential direction for communicating an inner space defined in the outer rotor (2) to the negative-pressure chamber (6). A shield member (21) is formed on the inner rotor (5) for intercepting the air vent through-holes (8) from the negative-pressure chamber (6) except for those located in a predetermined region opposite the delivery passage (20).
