ABSTRACT:
A fiber bundle produced by feeding combed fibers into a rotating rotor to accumulate the fibers over the inner circumference of the rotor is drawn out therefrom and is introduced into a false twisting unit, where the fiber bundle is false-twisted so that the twists are transmitted to a portion of the fiber bundle adjacent to the fibers accumulated over the inner surface of the rotor. A guide funnel having a guide surface extending near to the fiber accumulating surface is disposed within the rotor.
