PURPOSE: An injection nozzle for a water jet weaving machine is characterized by having many weft feeding holes on a needle, rotating separatively a connecting piece and cutting the weft on an end of the nozzle by cutting blades. The injection nozzle is capable of feeding selectively many pieces of weft from one needle, fixing accurately a position of the needle, preventing tangle of residual weft and increasing productivity. CONSTITUTION: The injection nozzle for the water jet weaving machine is comprised of: the needle(300) inserted into a hollow part(210) of a main frame(200); the weft feeding holes formed in a body(301) of the needle(300); the cutting blade(237) fixed in an end of the main frame(200); and a rotating body(250) which is installed on an outside of the main frame(200), containing the cutting blade(251).
