Problems solved by technology

[0005] EP0725175B1 discloses a nozzle beam for processing textiles with water jets. For uniform water pressure, a slit is arranged upstream of the discharge hole in the nozzle plate, and an enhanced water vortex that uniformly impacts the nozzle plate is generated from the inside. For this reason, with an increase in pressure loss

Embodiment Construction

[0021] figure 1 shows a cross-sectional view of a nozzle bar 1 for processing fibers, such as textile webs, with water jets, and figure 2 Shows a sectional view of the nozzle beam 1 along the section line A-A, wherein the section line A-A intersects figure 1 nozzle beam. Combine below figure 1 and figure 2 The nozzle beam 1 will be further described.

[0022] The housing of the nozzle bar 1 has an upper part 10 which is screwed to a lower part 16 multiple times over its length by means of threaded fasteners 24 . The upper part 10 has two longitudinally extending perforations 11 and 13 , wherein the upper perforation 11 forms a pressure chamber and the lower perforation forms a pressure distribution chamber 13 . The pressure chamber 11 and the pressure distribution chamber 13 are open at the end of the upper part 10 and the pressure chamber 11 and the pressure distribution chamber 13 are closed liquid-tight with the closing element 22 and 23 . The closing element 22 for...
