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 chambers 14, 16 for 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.
Claims19
A heald shaft for weaving machines, particularly for rapidly operating weaving machines, comprising
- an elongated base body formed as a hollow profile body and having two side walls which are interconnected by a web;
- the base body further having at least one first chamber and at least one second chamber, each being open at least at one side,
- a first stiffening body occupying the entire width of the base body between the two sidewalls and being disposed in the first chamber;
- the first stiffening body being glued at least at two sides to the base body, and
- a second stiffening body occupying the entire width of the base body between the two side walls and being disposed in the second chamber;
- the second stiffening body being glued at least at two sides to the base body.
A heald shaft for weaving machines, particulary for rapidly operating weaving machines, comprising:
- an elongated base body formed as a hollow profile body and having two side walls which are interconnected by web' with the base body further having at least one first chamber and at least one second chamber, each being open at least at one side;
- a first stiffening body occupying the entire width of the base body between the two sidewalls and being disposed in the first chamber, with the first stiffening body being glued at least at two sides to the base body;
- a second stiffening body occupying the entire width of the base body between the two side walls and being disposed in the second chamber, with the second stiffening body being glued at least at two sides to the base body;
- and wherein
- at least one of the stiffening bodies has at least one wedge-shaped end.
A heald shaft for weaving machines, particularly for rapidly operating weaving machines, comprising:
- an elongated extruded base body formed as a hollow profile body having two spaced side walls that are interconnected by at least one web to provide a plurality of chambers between the sidewalls, with at least a first of said chambers and a second of said chambers each being open at least at one side;
- a first stiffening body disposed in the first chamber and occupying the entire width of the base body between the two side walls, with the second stiffening body being glued at least at two sides to the base body;
- a second stiffening body disposed in the second chamber and occupying the entire width of the base body between the two side walls, with the second stiffening body being glued at least at two sides to the base body.
