Abstract
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.

Apparatus for selectively introducing one or more of a plurality of weft threads to the weaving compartment of an air jet loom comprising a single main air nozzle including an outer portion secured to a central body, a common central air chamber within said central body, and a delivery orifice extending from said central chamber for delivery of yarn from said central chamber to said main nozzle;
- said central body having a plurality of auxiliary orifices leading to said central chamber;
- means for supplying air under pressure to the exhaust opening of said main nozzle to draw a selected yarn therethrough;
- a plurality of feed nozzles each of which is mounted in operative communication with one of said plurality of auxiliary orifices;
- means for supplying air under pressure to a selected one of said feed nozzles to deliver a selected yarn therethrough;
- and a reversing means associated with each of said yarns for withdrawing the unselected yarns from said orifice.
