ABSTRACT:
To compensate for difference in path length between a warp thread guide element and a reference position, for example adjacent a take-up beam (3) beyond the shed (8), a plurality of guide elements (34) are located between a run-on guide rod (31) and the shed forming heddles (7), the guide elements being controlled to move in synchronism with the heddles in a direction essentially along a central plane (8a) of the shed to compensate for lateral deflection of the threads as the shuttle moves through the shed, and the shed is closed after the shuttle (9) has passed therethrough. The thread guide elements (37) preferably are U-shaped structures, retaining a plurality of transverse rods (39), and deflected by a cam shaft (42, 47) in synchronism with shuttle movement and movement of the heddles.
