At this time, in the first weft storage device DI, as shown in FIG. 2, a predetermined amount of weft yarn whose length has been measured and stored during about one cycle of inertial operation is stored. Further, the second weft storage device mD2 also stores the weft yarns whose weft insertion has been prevented.

。After this, the twist/id valve 7 explained in FIG. 1 is connected to the second main nozzle MN2, and the electromagnetic valve 9 is set to the "open" state, as shown in FIGS. 3(A) and (B). Fluid is injected from the second main nozzle MN2, and the weft W2 stored in the second weft storage device D2 is temporarily discharged from the second main nozzle MN2 toward the inside of the warp opening. At this time, the wefts W1 and W2 from the main nozzles MNI and MN2 are both continuous in the warp opening.

起動してやる。After the remaining yarns in all the weft storage devices are removed in this way, the loom is reversed to a position where it can be restarted. After that, preliminary winding of a predetermined number ♀ is performed. At this time, in this embodiment, as shown in FIG. 2, preliminary winding of a predetermined portion is performed only for the weft storage device DI. And preparation for restarting
That is, the weft cutting cutter 13 and the weft length measuring and storage device Di,
While returning D2 to the active state y island, '11! , set the magnet/help 9 to "close" and restart machine a using the prescribed restart method.

何様なものであってもよいことはいうまでもない。Note that the fluid circuit for causing the weft to fly toward the inside of the warp opening from the second main nozzle MN2, which is not currently used for weft insertion, as described in 1-, is not limited to the one shown in FIG. It goes without saying that any type of device may be used as long as it is used to carry out the present invention.

機構が簡単となり僅かな改変で済む。It goes without saying that when fluid is jetted from the second main nozzle MN2, which is not currently being inserted, it may also be jetted from the first main nozzle MNI, which is currently being inserted. In this case, the fluid circuit mechanism is simple and requires only a few modifications.

業７が簡略化できる。Furthermore, the present invention can also be applied to restarting the JIIS machine when it is stopped due to warp breakage. For example, when warp breakage occurs, #t1 machine stop F signal is generated at the same timing as in the above embodiment. At this time, if it is omitted to disable the cutter or set the weft gripper to the "closed" state as in the embodiment, when the loom is stopped, the weft W2 is continued from the second main nozzle MN2 into the warp opening. The state will be as follows. Thereafter, by injecting fluid from the first main nozzle MNI to temporarily discharge the weft yarn Wl into the warp opening, the same operation as in the above embodiment can be performed. This simplifies work 7 for restarting the loom when the loom is stopped due to warp breakage.

According to method N, the remaining yarn in the weft storage device on the main nozzle side that is not currently being inserted can be removed at the same time, so even if it is a multicolor weft insertion loom, restarting after stopping can be automated. No special workers are required for restarting, which not only greatly reduces personnel costs, but also improves the operating efficiency of the loom, making it possible to provide inexpensive multicolored woven fabrics.
