Abstract
An open-end spinning frame comprises a fiber feeding mechanism, constructed with a feed foller and a presser urged towards the feed roller, a combing roller having a metallic wire wound therearound, a rotor for spinning the fibers delivered from the combing roller, and a pair of flat side plates. The feeding mechanism is provided with a passage for flowing air current, which passage is formed by chamfering the side of the presser, by shortening the width of the feed roller or by forming only one projection at the front end of the presser. Through the air current flowing passage, one or more flow-in air currents flow so that the accumulation of fibers does not occur easily.
