<p>A set of parallel primary warp filaments are fed to a weaving location next to a set of parallel secondary filaments with a coupling element fed in between these two sets. The primary filaments shed between the two outer levels of a three-level shed, the coupling element sheds between one of these outer levels and the central level of the shed, and the secondary filaments shed between the other outer level and the central level. A pair of weft filaments are introduced as loops from the side of the shed corresponding to the secondary warp filaments, each waft filament being passed between a respective outer level of the warp and the central level. The free ends of the loops are caught by a picker and either hooked together, or a binding filament is passed through them. In this manner the one weft thread has at its inserting side a bight overlying the coupling element. The primary warp thread immediately adjacent the coupling element is of heavier weight than the other primary filaments as is woven oppositely to the coupling element.</p> |
