METHOD OF SETTING WEFT TRAVEL INFORMATION FOR AIR JET LOOM

The invention provides a method of setting weft travel information for an air jet loom including a weft-insertion device that executes a jetting operation of each sub-nozzle during weft insertion in a jetting mode set based on weft travel information including information that allows a weft travel status to be plotted in a travel line form in a graph region whose horizontal and vertical axes indicate a crank angle and a distance from a weft-insertion start position in a weaving-width direction, the method including setting first and second positions on a weft supply side and an opposite side in a travel passage from the start position to an arrival position; dividing the travel line into first to third continuous partial travel lines in first to third sections divided at the start, first, second, and arrival positions; and setting the weft travel information as including information about each partial travel line.
