Heddle frame with torque locking block center brace assembly

A heddle frame for supporting a plurality of heddles, said frame comprising:

• a top rail and a bottom rail extending longitudinally relative to the frame;
• end members connecting each end of said top rail and said bottom rail so as to form a generally rectangular frame structure therewith;
• a heddle bar supported on said frame wherein heddles are supported by said heddle bars within said frame structure;
• a center brace extending between said top rail and said bottom rail at a position between said end members for maintaining parallelism of said top and bottom rails, said center brace including
• an elongated center portion, and
• first and second flanges at opposite longitudinal ends of said center portion;
• and
• first and second locking blocks respectively attached to said top rail and said bottom rail and configured to respectively receive and cooperate with said first flange and said second flange and to exert forces on said first and second flanges to create opposing torques thereon, thereby placing said center portion in torsion and locking said first flange and said second flange within their respective locking blocks.
