ABSTRACT:
A weft inserting device using a profiled reed for an air jet loom is equipped with a plurality of reed pieces each having a C-shaped guide notch. The line of guide notches forms a weft passage where weft injected from a main nozzle flies. Each guide notch has a upper wall parallel to the floor surface on which the device is placed, a deep wall perpendicular to this surface, a lower wall which gradually becomes wider toward an opening, an upper connecting portion which connects the upper wall to the deep wall, and a lower connecting portion which connects the deep wall to the lower wall. The radius of curvature of the upper connecting portion is set equal to or smaller than 1 mm, and the radius of curvature of the lower connecting portion is set greater than the radius of curvature of the upper connecting portion.
