ABSTRACT:
A dual-face composite frame slat for a heddle frame of a loom includes a long-wall face (30) and a parallel short-wall face (32). Faces (30) and (32) are spaced from one another and define a core space (45) and upper and lower frame slat edges (36) and (38). Integral channel stiffeners (40) and (42) are interposed in the frame slat edges to provide integral beam structure. Faces (30) and (32) are constructed as a ten ply graphite reinforced plastic layup. Channel strips (40) and (42) have a four ply construction. A plastic heddle rod (22) is carried by a free flange portion (34) of the long-wall face and includes metal wear resistant caps (50).
