Abstract
A method of yarn piecing in a fasciated yarn spinning unit is disclosed by which a yarn having a broken end and drawn out from the yarn package is introduced through the false-twisting nozzle by conducting an intermediate portion of the yarn into a slit which is formed on a lateral side of the nozzle and extends to the yarn passage channel in the nozzle. Because the yarn has been previously cut into a predetermined length thereof, the cut end of the yarn is placed in the drafting zone of the drafting mechanism at a position where the cut yarn end overlaps a broken end of the fiber bundle. By restarting the spinning operation, the overlapping ends of the yarn and fiber bundle are drafted properly in the drafting zone and then the fibers in the overlapping ends are intermingled by the false-twisting effect of the rotary stream of jetted air while they are advanced through the false-twisting nozzle.
