Abstract: Weft yarn for weft insertion in a machine for non-woven fabrics with one or more sets of warp yarns is fed through an intermittent tensioning device to a rotating hollow wand through which the yarn passes and which lays successive wefts on hooks on weft carrying chains, the thread being transferred on one side to a first rotating finger which transfers it onto a second forked rotating finger which loops the yarn around a hook. Preferably, on one side, there are additional fingers which cause the yarn to make one half turn, and on the other side there is a rotating finger with two hooks which straddle the rotating forked finger and transfer the yarn to weft hooks on the traveling chain without turning the yarn. Tension is intermittently applied at the points where yarn is transferred from the wand to the fingers to prevent yarn overshoot.
