(54) Weft-insertion-condition display method for loom


(57) A loom includes a display device, and a weft arrival time is detected each time a weft insertion operation is performed in the loom. The display device calculates statistics regarding the weft arrival times for each of predetermined sampling periods on the basis of the detected weft arrival times, stores the statistics that are sequentially calculated during a weaving operation in time series, and graphically displays the stored statistics in time series along a time axis. Information regarding a cause of a variation in a travelling motion of a weft yarn (information regarding a replacement of a yarn supplier, information regarding a reset operation for resetting the weft-insertion operational condition, and information regarding a change in a weaving condition other than the aforementioned information) is displayed on the same screen as a display screen on which the statistics are displayed.
