Abstract
A jet bar on a device for producing streams of liquid for jet interweaving of the fibers of a fiber web guided along the bar includes an upper part that extends over the operating width of the fiber web and a lower part fastened thereto in a liquid-tight manner. In the upper part and extending over its length, a pressure chamber is located which receives liquid that is under pressure, endwise for example. Parallel thereto, with an intermediate partition, a pressure distribution chamber is provided which is connected with the pressure chamber by throughflow holes for liquid extending through the intermediate partition. A jet sheet with holes for forming jets of liquid is mounted in a liquid-tight fashion on the lower part. In order to achieve a better equalization of the pressurized fluid entering the pressure distribution chamber, the pressure distribution chamber terminates in an area opposite the liquid throughflow holes in a slot that is narrow by comparison with the cross section of the pressure distribution chamber, said slot terminating close to or in proximity to holes in the jet sheet. The jet sheet is mounted in a liquid-tight fashion by means of a sealing O-ring. This O-r…
