ABSTRACT:
A heald shaft for weaving machine has a shaft rod (3) which is formed of a one-piece light-metal profile and two stiffening bodies (24, 25) glued to the shaft rod (3). The stiffening bodies bridge the entire width of the shaft rod (3), wherein the width is measured between the side walls (11, 12). The chambers14, 16for receiving the stiffening bodies (24, 25) each have at least one open side through which the stiffening body is visible from the outside and through which it may be introduced into the respective chamber (14, 16). This construction facilitates manufacture. Further, a rigidity in the working direction, as well as a good rigidity transversely thereto is achieved.
