Abstract: A jacquard type loom for making a fabric by weaving plural warp yarns with plural weft yarns, the fabric including a determined number of columns of warp yarns per unit length and a determined number of layers of weft yarns. The loom includes a comber board including plural holes passing a corresponding number of control cords, each control cord including an heddle eye through which a warp yarn passes. The holes are distributed in a determined number of columns extending parallel to the warp yarn direction and a determined number of rows per column extending in a direction perpendicular to the warp yarn direction. The comber board includes a number of columns of holes per unit length smaller than the number of warp columns in the same unit length in the fabric, and a number of rows of holes greater than the number of warp layers in the fabric.

Abstract: A corner fitting preform and a method of forming a corner fitting preform including steps integrally weaving a base or parent material with one or more flanges or legs that extend from the base is disclosed. The flat woven preform includes specially engineered areas within the legs or flanges that have continuous warp yarns which are not woven. The unwoven areas provide a hinge which allows the flanges of the preform to fold around a corner. After folding, the excess unwoven warp yarns are pulled back through the woven portion of the legs or flanges to produce a preform with continuous warp yarn reinforcement around the corner.
