The weft-finding action of Dornier rapier loom is an automatic program, which is automatically executed when the weft-breaking occurs and starts after the weft-breaking occurs. Start the loom for positioning parking, the rapier clutch on both sides is detached, the weft insertion action is stopped, and the other loom agencies retreat one weft. Then the rapier clutch on both sides engages, and the loom can be started again after removing the broken weft in the shuttle. As long as the weft-finding button is pressed, the automatic weft-finding program can be repeated.
