Abstract (en)
[origin: WO9623921A1] A method for making a nonwoven fabric lap using pressurised water jets, wherein the lap (10) is positively fed over an endless porous support (1), delivered to a perforated rotary cylindrical drum (20), and squeezed between the porous support (1) and the rotary drum (20), and a water curtain (31) is sprayed onto the lap, whereafter the elemental fibres are entangled by spraying a row of high-pressure water jets (42, 43, 44) onto the resulting wet squeezed lap (40). An apparatus for carrying out the method is also disclosed.
