<p>PURPOSE: To provide the subject device capable of surely guiding weft yarns by forming a planar jet flow for distributing air so as to follow a thin flat belt like body of a flowing out fluid at the side of a central jet flow core reinforced within a jet flow width. CONSTITUTION: This air pressure type weft yarn-inserting device is provided by jetting a planar jet flow 6 from a supporting nozzle 4 toward the next supporting nozzle 4 in its dashing direction to make the jetting direction of the continuous planar jet flow parallel or concentric. The distribution of the air in its jet flow thickness, has a central core having somewhat reinforced planar jet flow 6 and a thin planar jet flow (a thin belt like body) following at the side of the core.</p> |
