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.

A method for setting weft insertion conditions is used in a multi-color weft insertion loom including a weft insertion device (11) which includes weft insertion systems which each include weft-insertion-related devices, a setting device (46) which sets a weft insertion pattern defining selection numbers of the respective weft insertion systems and operation control values of the weft-insertion-related devices belonging to the respective weft insertion systems, and a weft-insertion control device (43) which stores the weft insertion pattern and the control values corresponding to the selection numbers and causes the weft-insertion-related devices to perform weft insertion in accordance with the control values. The method includes a step of allowing an operator to select two weft insertion systems corresponding to weft yarns to be replaced by each other by using the setting device, and a step of causing the setting device to execute, in response to a generation of a switch command signal based on the above-mentioned step, an operation of switching the control values of the weft-insertion-related devices that are switch targets for the selected two weft insertion systems.

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 change in a weaving condition is displayed on the same screen as a display screen on which the statistics are displayed. The information regarding the change in the weaving condition includes an input history regarding a change in a setting of the weaving condition.

A loom in which a weft arrival time is detected each time a weft insertion operation is performed includes a weft-insertion-condition display apparatus (20). The weft-insertion-condition display apparatus (20) calculates statistics (average, maximum and minimum values, and standard deviation) regarding weft arrival times detected in 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. An occurrence status of stoppages of the loom that have occurred in each of the predetermined sampling periods is displayed such that the number of stoppages can be visually recognized along the same time axis as the time axis along which the statistics are graphically displayed.
