WEFT YARN MIXING DEVICE FOR SHUTTLELESS LOOMS

In a shuttleless weaving loom wherein the weft yarn transfer is effected according to the so-called "Gabler" system, a device for mixing two weft yarns under the control of a pair of cams acting upon respective yarn guides through the medium of a lever pivotally connected to a pair of adjustable links, one pivoted to an arm above the pivot axis thereof, the other to another arm but beneath the pivot axis thereof, one arm being movable from its operative position to its inoperative position, and vice versa, a positioning bent fork controlled by another cam being provided for engaging the weft yarn moving past said fork and to lower same to an operative position in which it can be picked up by an insertion member, with a very smooth movement precluding any damage to the yarns.
