<p>PROBLEM TO BE SOLVED: To provide a method and device for displaying weft insertion information which are used for providing an operator with information (indicators) helpful in adjustment work in a water jet loom having a weft insertion nozzle fixedly arranged on a loom frame.SOLUTION: Graphic displays of the flying trajectory of a weft yarn and the oscillation trajectory of a reed are displayed while being superimposed on a graph area where the horizontal axis indicates the rotation angle of the main shaft of a loom on a display screen. In addition, at least the end point of a weft insertion effective period during which the weft yarn is effectively transferred by a water jet is determined, and the determined end point is displayed on the display screen in such a way that the rotation angle of the main shaft can be acquired.</p> |
