ABSTRACT:
An apparatus for producing a fasciated yarn comprising two air nozzles (2, 3) arranged at an angle in such a manner that a wedge shaped space (S) is formed therebetween, in which each of the air nozzles (2, 3) has a function of rotating a fiber bundle about the axis thereof in a direction that is the reverse of the other. A yarn passage from the first air nozzle (2) and to the second air nozzle (3) is so adapted that the fiber bundle is not in positive contact with an inner wall of an exit portion (7) of the first air nozzle (2) but is in contact with an inner wall of an inlet portion (4) of the second air nozzle (3), whereby a twist ascent from the second air nozzle (3) into the first air nozzle (2) is adequately suppressed and effective fasciated yarn forming is attainable. According to the wedge shaped space (S), the interference by exhaust air from the first air nozzle (2) with the second air nozzle (3) is eliminated.
