Abstract
A guide for the to-and-fro motion of a pair of weft carrying grippers inside the shed of weaving looms with continuous weft feed, of the type comprising two control straps movable in a substantially horizontal plane thanks to the action of two gearwheels with reciprocating motion, and a plurality of guide elements for the straps, aligned on the sley facing the reed and positioned perpendicularly thereto. The strps have at least one undercut groove and the guide elements are open and form pairs of bilateral guides for the straps, of which they engage the undercut groove. The guide elements are suitably hook elements, open towards the reed, and the straps project out of these elements towards the reed, the pairs of bilateral guides each operating according to at least two orthogonal planes.
