ABSTRACT:
A nonwoven product is made by passing a fiber web longitudinally along a treatment path and preconsolidating it at an upstream location along the path. Then the web is fully consolidated by liquid jets downstream of the location at longitudinally spaced and transversely extending discontinuous strips each interrupted at least two break points. The web is then fully consolidated by liquid jets downstream of the location at least two transversely spaced longitudinally extending strips extending a full length of the web and crossing the transverse strips at the break points. Subsequently the web is cut up into pieces along the strips.
