ABSTRACT:
A heddle frame for supporting a plurality of heddles includes a top rail and a bottom rail extending longitudinally relative to the frame. End members connect the top rail and bottom rail so as to form a generally rectangular frame structure. A heddle bar is supported on the frame structure wherein heddles are supported by said heddle bars in the frame structure. A center brace extends between the top rail and the bottom rail at a position between the end members for maintaining parallelism of the top and bottom rails. The center brace includes an elongated center portion and first and second flanges at opposite longitudinal ends of the center portion. First and second locking blocks are respectively attached to the top rail and the bottom rail and are configured to respectively receive the first flange and the second flange and to exert forces on the first and second flanges to create opposing torques thereon. This places the center portion in torsion and locks the first flange and the second flange within their respective locking blocks.
