Abstract: An apparatus for assisting a weft picked into a shed by main nozzle of a jet loom in being inserted through the shed properly is provided. The apparatus comprises improved auxiliary nozzles, each of which has formed therein a first outlet opening for discharging weft pick assisting jets of fluid therethrough and a second outlet opening for discharging weft pick stabilizing jets of fluid therethrough, said first and second outlet openings being arranged in spaced relation to each other along the axis of said auxiliary nozzle and also in such a way that the axes of said first and second outlet openings will form an angle thus directing in different direction from each other so that harmful turbulence of fluid due to interference thereof may be prevented successfully from taking place.
