Abstract: A weft guidance tube for a fluid weft insertion system of weaving apparatus includes an elongated member having a longitudinal channel therein. A plurality of segments are juxtaposed in the channel. Each of the segments includes a base and an upper end, with the upper end having an aperture therein and an exit slot extending from the aperture. The base of each segment is wider in cross-section than the upper end thereof. Connecting pins project outwardly from one side of each base to thereby permit connection of adjoining segments to each other. When so connected the apertures and exit slots of all of the segments arranged in the channel are in proper alignment and the upper end of each segment is spaced apart from the upper end of adjoining segments by a distance goverend by the width of bases of the segments. The plurality of segments are secured to the channel by suitable gripping means.
