A single main air jet nozzle includes an outer portion secured to a central body. The central body includes one main orifice which delivers yarn to the main nozzle, and a plurality of weft thread introducing feed orifices. Each feed orifice includes a feed nozzle at the entrance thereto. There is thus provided for the selection of one or more weft threads to be introduced through the introductory or feed nozzles and into the main orifice, and then to the main nozzle from which the yarn is blown into the weaving compartment of an air jet loom. The unselected yarns are held back by a braking or reversing apparatus until selected.
