<p>A picking channel for pneumatic jet looms with auxiliary blowing sections disposed across the weaving width and consisting of at least three auxiliary blowing nozzles the relative positions of the axes of which being those of skew lines with the axis of the first auxiliary blowing nozzle crossing the axis of the weft thread under insertion. The axes of the other auxiliary blowing nozzles pass said axis of the weft thread under insertion of the outside, in the direction of the axis of the first auxiliary blowing nozzle. The various dispositions of both the auxiliary blowing sections and nozzles insure reliable weft insertion, and economic exploitation of the energy of the carrier medium and, consequently, a greater weaving width.</p> |
