Abstract
A heddle shaft is formed of a hollow metal profile section into which an expanding element for vibration damping is inserted. The expanding element is for example a precompressed foam strip which expands after insertion into the internal chamber of the hollow metal profile section until it is seated with a certain initial tension between the side walls of the hollow metal profile section. It is embodied as a solid (non-liquid) body and is introduced as such into the internal chamber. For being locked in place, it can be provided with adhesive faces.
Claims15
A heddle shaft rod for heddle shafts of power looms, comprising an elongated hollow metal profile section, which has two side walls between which at least one internal chamber is embodied,
- an expanding element which is located in the internal chamber and which rests with initial prestressing against the side walls;
- and
- wherein the expanding element, in an original previously compressed state, has a thickness (D) which is less than the spacing A between the side walls.
A heddle shaft rod for heddle shafts of power looms, comprising:
- an elongated hollow metal profile section, which has two side walls between which at least one internal chamber is formed;
- an expanding element, which is located in the internal chamber and which rests with prestressing against the side walls, and is joined by material to material engagement to both side walls;
- and,
- a mask is located between the expanding element and the side wall.
