摘要： A weft inserting nozzle including a weft inserting first hole through which a weft yarn is passed, an annular air jet opening defined around the exit of the first hole, and a weft inserting second hole extending coaxially and downstream from the annular air jet opening is disclosed. The second hole consists of an upstream positioned first section and a downstream positioned second section each having a uniform diameter throughout the length thereof, the diameter of the second section being greater than that of the first section which is equal to the outer diameter of the annular air jet opening.
