ABSTRACT:
A lightweight shear-resistant frame slat (A) is disclosed for use with a heddle frame assembly (10). The frame slat includes a thin wall, roll-formed steel back plate (B) and a thin wall, roll-formed steel front plate (C). A first ledge (38) is formed on the back plate (B) and a second ledge (54) is formed on the front plate (C). The ledges (38) and (54) are spaced apart to define a heddle rod mounting socket (62) which receives a stem (63) of a heddle rod (20) to mount the heddle rod with reduced shearing forces on the frame slat. A box shaped core space (58) is formed between the front and back plates in which a honeycombed structure (66) is disposed for increasing the stiffness of the frame slat. A reduced neck portion (50) is formed between the mounting socket (62) and the core space front and back sides are flush with each other and may be secured by any suitable means such as adhesive bonding.
