Abstract
A rotor type open-end spinning unit in which in order to prevent blowing of air to the rear of an outlet of a fiber transporting channel formed in a spinning body and impingement of an air stream from the fiber transporting channel against the back face of a separator, the rear end of the outlet of the fiber transporting channel on the central side of a rotor is expanded forward of an imaginary line, connected between the rear end of the channel outlet furthest from the center of the rotor and the center of the rotor, and the angle .alpha. between the face of the fiber transporting channel confronting the combing roller and the plane intersecting the axis of the rotor at a right angle is made substantially equal to the taper angle .theta. of the back face of the separator.
