ABSTRACT:
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).
