Document Type and Number:
Japanese Patent JP2660556
Kind Code:
B2
Abstract:
In a weft insertion system of an air jet loom, a weft passage in the form of a U-shaped groove opening forwardly toward a cloth fell is formed by recesses of profiled reed dents, and sub-nozzles are arranged to direct auxiliary air jets into the weft passage. In order to obtain a desirable air stream in the weft passage, and to prevent a weft yarn from flying out of the passage, an upper edge of each recess, bordering the recess on the upper side, is inclined so that a distance from an axis of swing motion of the reed becomes gradually smaller toward the open end of the recess. Furthermore, an innermost edge of each recess is inclined so as to intersect at an angle with a straight line passing through the axis of swing motion.
