An apparatus for inserting a false twist in roving or yarn as the strand or strands of fibers are fed from between a pair of front rolls to a takeup device. The apparatus includes a rotor rotatably carried in an enclosing casing. A plurality of circumferentially spaced air entrapping members is provided in the perimeter of the rotor so that upon applying pressurized air to the members, the rotor is driven. A yarn conveying tube extends axially through the rotor and is fixed thereto for being rotated therewith. A portion of the yarn conveying tube is radially disposed from the rotational axis of the rotor so that as the yarn flows through the rotating tube, a false twist is inserted in the yarn from the tube up to the nip of the front rolls.
