In a shuttle-less loom in which a pick of weft is inserted into the shed of warp yarns by a jet of compressed air from an insertion nozzle to one side of the shed, a plurality of spaced auxiliary nozzles are provided along the weft path through the shed. Each auxiliary nozzle has a horizontal slot directly below the weft path, and a vertical slot at one or both ends of the horizontal slot adjacent the respective lower end of the vertical slot. The slots face in the direction in which the weft travels and are supplied with compressed air to provide a lower substantially horizontal flat jet of air from the horizontal slot and one or two lateral jets from the respective vertical slot, so that the air jets serve to guide, support and augment the propulsion of the weft.
