<p>A heddle frame (10) having a pair of hollow laterally extending cross rails (12, 14) and a pair of end braces (16, 18) connected to adjacent ends of said cross rails (12, 14) to form a rectangular frame (10). The connection between the end braces (16, 18) and the laterally extending cross rails (12, 14) comprise a projection (24) which extends at right angles from the end brace (16, 18) and fit into an elongated opening within the hollow cross rails (12, 14). The projection (24) has a width which is less than the width of a opening into which it extends and includes means (22) for resiliently connecting the projection to the walls of the hollow rail to provide a connection between the end brace (16, 18) and the cross rail (12, 14) which is rigid when not under stress but permits limited relative movement between the cross rails (12, 14) and the end brace (16, 18) whenever the cross rails are under stress. The resilient connection (22) includes an insert (26) of a synthetic plastic, elastomeric material such as polyurethene into which is fitted two or more bushings (28) for the reception of metal fastener means (30) which fastens the insert (26) securely to the walls of the hollow cross rail (12, 14).</p> |
