Weft inserting channel for pneumatic weaving machines, the channel being disposed in the shed and consisting of active and passive sections provided with a weft inserting opening and a directing profile for centripetally directing both the main and the additional pressure air jets in the direction of weft insertion. The radial distance of the directing profile from the axis of the weft inserting channel of at least one passive section adjacent an active section in the direction of weft insertion is equal to or longer than the radial distance of the separate points of connecting line of the tangential point of the directing profile of the following active section with the point of intersection on the front wall of the preceding active section while the radial distance of such point of intersection from the axis is longer than the radial distance of the discharge openings.
