Abstract
In an open-end spinning apparatus provided with a fiber feed mechanism, a combing roller for separating a bundle of fibers supplied from the feed mechanism into individual fibers, a spinning rotor for receiving individual fibers delivered from the combing roller and for forming a ring shaped bundle of fibers on a fiber collecting zone formed at an inside wall position having a maximum lateral diameter with respect to a rotational axis thereof, and a yarn guide means for introducing a yarn formed in the spinning rotor toward a takeup mechanism disposed at a position outside the spinning rotor, a plurality of air streams are directly blown toward the fiber collecting zone by means of air stream creating means so that the ring shaped bundle of fibers deposited on the fiber collecting surface is urged toward the inside wall of the rotor at this collecting zone by the action of the air stream together with the centrifugal force of the fibers which is created by the rotation of the spinning rotor.
