Abstract (en)
[origin: EP1908855A1] A web of non-woven felt fibres is strengthened by exposure to an array of high-pressure water jets. The water jets are apertures in a strip located within a surrounding frame. The jet strip is a section of martensite hardened sheet metal of strength greater than 46 HRC and incorporating nitrogen at the outer margins. The high-alloy X20Cr13 steel is thermally hardened to above 53 HRC. In a further embodiment the steel is a combination of austenitic and martensite steel. Each jet consists first of a cylindrical section, followed by a diverging outlet.
