ABSTRACT:
A weft picking device of an air jet loom, comprises a plurality of air guide members spaced one from the other and in alignment with the direction of weft insertion. Each air guide member is formed with an air guide opening which forms part of a weft guide channel. Additionally, a plurality of auxiliary nozzles are disposed at certain intervals along the weft guide channel. Each auxiliary nozzle is in the shape of a hollow rod and formed at the wall thereof with an air ejection opening. The outer diameter of each auxiliary nozzle is smaller than the thickness of the air guide member. At least an upper part, having the air ejection opening, of the auxiliary nozzle is located between two opposing planes defining the thickness of the air guide member, thereby preventing the warp yarns from rubbing contact with the auxiliary nozzles.
