Abstract
A fiber control apparatus in an open-end spinning frame is disclosed. According to the invention, in an open-end spinning unit having a fiber passage through which fibers opened by the combing roller are carried into the spinning chamber of the rotor, one or more nozzles are provided in the unit, each nozzle having an outlet opening located adjacent to the fiber outlet opening of the fiber passage so that one or more streams of jet air, emitted from the nozzle or nozzles, direct and guide the fibers introduced into the chamber toward the interior peripheral surface of the spinning chamber of the rotor, thus causing the fibers to reach said surface immediately without being slowed or bent by ambient air streams within the chamber. Consequently, formation of yarn having bent or randomly attached fibers is substantially prevented, whereby the strength and quality of the spun yarn is greatly improved.
