Abstract (en)
The invention provides a method of setting weft travel information for an air jet loom, a jetting mode of each sub-nozzle (S) being determined based on weft travel information about an expected weft travel status allowing the weft travel status to be plotted in a travel line form in a graph region whose horizontal and vertical axes indicate a rotational angle of a loom main shaft (15) and a distance from a weft-insertion start position in a weaving-width direction, weft insertion being executed under weft-insertion conditions including the jetting mode and a target weft arrival timing. The method includes setting first and second positions on weft-supply and opposite sides; determining that the travel line is bent at first and second bend points at the first and second positions; and setting the second bend point using the rotational angle based on the target weft arrival timing, and the second position.
