Abstract (en)
[origin: EP3936649A1] A weft yarn tensioning device (40) of an air jet loom in which a weft yarn (23) is inserted along a weft yarn guide passage (11) formed in a reed (10). The weft yarn tensioning devise (40) includes a weft yarn travel passage (50) extending along the weft yarn guide passage (11), a first air discharge member (63) configured to discharge an air in a direction along the weft yarn travel passage (50), a second air discharge member (74) configured to discharge the air in a direction different from the direction along the weft yarn travel passage (50). The first air discharge member (63) discharges the air to introduce the weft yarn (23) into the weft yarn travel passage (50), and the second air discharge member (74) discharges the air to the weft yarn (23) in the weft yarn travel passage (50).
