Abstract (en)
A weft insertion device of an air jet loom (1) includes a modified reed (40) having a weft yarn travel passage (41), a main nozzle (22) from which air is discharged toward an inlet (41a) of the weft yarn travel passage (41) to inject a weft yarn (11) into the weft yarn travel passage (41), and an inducing nozzle (60, 60a, 66) disposed in parallel with the main nozzle (22) and from which air is discharged to the inlet (41a) of the weft yarn travel passage (41). A timing at which air discharge from the inducing nozzle (60, 60a, 66) starts is prior to a timing at which air discharge from the main nozzle (22) starts.
