Abstract
An apparatus for inserting a weft into a shed by jetting fluids in a jet loom comprises a plurality of thin plate-like members arranged in alignment in the direction of weft insertion on a sley, each of the thin plate-like members being provided with an opening in the same position of each of said thin plate-like members to form a guiding channel, and nozzle means for jetting fluids through the guiding channel. Each of the thin plate-like members is provided with at least one cavity which is formed adjacent the circumference of each of the openings of the thin plate-like members on a downstream sidewall, in the direction of weft insertion, of the mutually facing sidewalls thereof. Due to the formation of the aforesaid cavity, the amount of the fluid flow escaping through the space between each two adjacent thin plate-like members outside of the guiding channel without narrowing the width of the space therebetween. As a result, the flight of the weft is remarkably stabilized and the flying speed of the weft is increased with reducing the consumption of fluids jetted from nozzle means.
