Abstract (en)
[origin: CN101444766A] The present invention relates to a nozzle bar for generating fluid beam when consolidating non-woven fabric. The nozzle has a metal plate, which exhibits a number of nozzle openings, which are arranged next to each other between an upper inlet surface and a lower outlet surface. The nozzle openings are formed by a nozzle hole, where the nozzle hole extends from the inlet surface to the outlet surface on the metal plate and is formed by a plurality of continuous transitional hole segments. In order to obtain a spraying beam with maxmium kinetic energy as accurate as possible, the nozzle hole of the invention has three boring sections, where the first boring section forms a capillary zone for bundling the fluid jet. The middle section forms an expansion zone for widening the fluid jet. The third section forms a discharge zone for guiding the fluid beam.
