METHOD AND APPARATUS FOR COMMENCING THE YARN FORMING OPERATION OF A FASCIATED YARN ABSTRACT OF THE DISCLOSURE An improved method for commencing the yarn forming operation of a fasciated yarn and an apparatus for carried out thereof. In the apparatus for manufacturing a fasciated yarn from a bundle of fibers supplied 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 pre- determined 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. -1-
