Abstract
A novel method for yarn piecing in a fasciated yarn spinning unit, in which a broken end of a yarn and the fiber bundle to be pieced together are nipped and intermingled with each other between a soft nipping area between middle top and bottom aprons and thereafter are false-twisted by a vortex in an air nozzle. Motions of the associated parts are controlled as so to be able to achieve a suitable overlapping length of the yarn and the fiber bundle in the nipping area of the aprons.
