WEFT INSERTION NOZZLE OF FLUID INJECTION-TYPE WEAVING MACHINE TO PREVENT DEFECT OF TEXTILE

摘要

PURPOSE: A weft insertion nozzle of a fluid injection-type weaving machine is characterized by optimizing the number of a commutating groove on a commutating element. CONSTITUTION: A weft insertion nozzle of a fluid injection-type weaving machine comprises: a needle(1) having a yarn guide hole(14) and inserted into a hollow part(3); a nozzle main body(2) containing a feed water hole(13) perforated into the hollow part(3) and a circular channel connected with the feed water hole(13) between the needle(1) and the same; commutating elements(5,6) installed on the circular channel at regular intervals in order of direction advanced weft; and plural commutating paths formed continuously in an axial direction.
