Abstract
In the piecing operation, the broken ends of a yarn and a fiber bundle are sucked into a suction nozzle, and therein are entangled due to twists imparted to the fiber bundle by first vortices utilized for forming a fasciated yarn. The broken end of the yarn may be twisted in reverse of the fiber bundle by second vortices. Further, third vortices weaker than the first vortices may be used instead of the first vortices. The apparatus comprises jets for generating the second and third vortices and piping for transporting air to the jets and from the suction nozzle, as well as a control circuit thereof.
