Abstract

A heddle shaft (1) has shaft rods (2, 3), which are embodied as profile bodies (12) having at least one hollow chamber (14). The shaft rods (2, 3) are joined together by lateral bracing posts (4, 5) and at least one center connector (11). For securing the latter, retaining pieces (23) are disposed in the hollow chambers and are accessible through windows (22). The retaining pieces (23) are preferably glued into the hollow chamber (14) and have one or more threaded bores for securing the center connector (11) by means of screws (37).
