Abstract (en)
[origin: CN115029868A] The invention relates to a nozzle strip for generating a fluid jet for the hydrodynamic reinforcement of a material web, comprising a plurality of nozzle holes arranged at a distance from one another in at least two rows for applying a fluid jet to the material web, the nozzle holes being introduced as inclined holes into the nozzle strip, the nozzle strip is configured in such a way that the longitudinal axes of the nozzle holes of the same row directly adjacent to each other and the longitudinal axes of the nozzle holes of the directly adjacent row directly opposite to each other extend obliquely relative to each other. The invention further relates to a device for reinforcing a material web, comprising at least one nozzle bar and a nozzle strip which can be connected to the nozzle bar in a fluid-conducting manner for generating a fluid jet for hydrodynamically reinforcing the material web, the nozzle strip being designed according to the invention.
