  • the device each consists of a nozzle bar (water bar), which has on its underside a nozzle strip with a plurality of outlet openings for a pressurized medium, in particular water.
  • the woven, knitted fabric or nonwoven fabric (nonwoven) which is preferably transported in the form of a web under the nozzle bar, is acted upon by the pressurized water jets.
  • a nonwoven such a solidification or entanglement of the fibers or filaments can be produced.
  • the known nozzle beam consists of a steel body whose length corresponds to the maximum working width of the machine. In the body from one end face to the end extending bore is introduced, which forms a pressurizable water chamber. On the underside of this body a Düsenstre- fen is arranged with outlet openings, which is attached via a designated as a jaw part by means of screws on the body of the water bar. About holes, the outlet openings of the nozzle strip from the chamber of the beam ago pressurized water.
