ABSTRACT:
A guide for the motion of a pair of weft grippers inside the shed of a shuttleless loom, in which two control straps each carrying one of the grippers move on a substantially horizontal plane under the action of two gearwheels with reciprocating motion. A plurality of elements guide the straps in this motion, these guide elements being aligned on a sley facing a reed of the loom and positioned perpendicularly thereto, the straps having a substantially rectangular section of greater width than thickness and a shaped recess extending along each longitudinal side edge. The guide elements are substantially horizontal tooth projection, shaped like and engaged in those recesses. The projections are wedge-shaped, the apices of the wedges being substantially half way along the thickness of the straps. The straps are wider and thicker adjacent the grippers than remote from the grippers.
