ABSTRACT:
Disclosed is an open-end spinning apparatus provided with a fiber-bundle supply mechanism disposed to a casing and a combing roller disposed in the casing, so as to separate the supplied bundle of fibers into individual fibers, and a spinning rotor for forming a yarn from said individual fibers; a fiber carrying passage is formed in the casing at a position between the fiber-bundle supply mechanism and the spinning rotor, the fiber carrying passage being provided with a combing section where an action of the combing roller is imparted to the bundle of fibers delivered from the fiber-bundle supply mechanism so that the fibers of the fiber-bundle are separated from each other from; a pneumatic or mechanical means is provided for positively introducing the above-mentioned individual fibers to a part of the cylindrical surface of the combing roller; so that, consequently, all fibers contained in the bundle of fibers fed from the fiber-bundle supply mechanism receive effective combing action of the combing roller in the combing section of the fiber carrying passage.
