An improved spinning apparatus for making textile fiber yarn, carrying a hollow rotor provided with inlet and outlet passages, a feeding device for driving a fiber bundle from a certain power source towards said hollow rotor, means for releasing fibers of said fiber bundle with a pneumatic fluid stream, means for driving the rotor at a high rotational speed and means for collecting fibers, again bundled, from the hollow rotor at the same time as they are subjected to torsion, characterized by the improvements consisting of including means for driving the fiber bundle from the power source to the hollow rotor, by a pneumatic suction flow produced by the introduction of compressed air, and means for positively releasing individual fibers from the fiber driven beam, in a certain position located between the power supply and the entrance passage of the hollow rotor, they the ejection against such fiber bundle of a pneumatic flow directed to a determined position of the inner peripheral wall of the hollow rotor; said driving and releasing means being arranged in the feeding device and receiving the end discharge portion of the second ones by the input passage of the rotor.
