ABSTRACT:
An improved method for commencing the yarn forming operation of a fasciated yarn and an apparatus for carrying it out thereof. In the apparatus for manufacturing a fasciated yarn from a bundle of fibers suppled from a supply mechanism into a yarn forming mechanism provided with a fluid nozzle, when the yarn forming operation is commenced, the distance between the downstream nip point of the fiber bundle supply mechanism and a twisting point of the fluid nozzle is shortened in a condition shorter than a predetermined distance such as an effective fiber length of a material fiber, and after completion of such initial yarn forming operation, the above-mentioned distance is gradually or stepwisely enlarged to the distance wherein a normal yarn forming operation is carried out. Such shortening and enlarging the above-mentioned distance is carried out by displacing the fluid nozzle and/or changing the position of the downstream nip point of the fiber bundle supply mechanism.
