Abstract
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.
