Claim Text:
1. A process for forming a fluid-entangled laminate web having projections comprising: providing a projection forming surface defining a plurality of forming holes therein, said forming holes being spaced apart from one another and having land areas therebetween, said projection forming surface being capable of movement in a machine direction at a projection forming surface speed, providing a projection fluid entangling device having a plurality of projection fluid jets capable of emitting a plurality of pressurized projection fluid streams of entangling fluid from said plurality of projection fluid jets in a direction towards said projection forming surface, providing a support layer, said support layer having an opposed first surface and a second surface, providing a nonwoven projection web comprising fibers, said projection web having an opposed inner surface and an outer surface, feeding said projection web onto said projection forming surface with said outer surface of said projection web positioned adjacent said projection forming surface, feeding said second surface of said support layer onto said inner surface of said projection web, directing said plurality of pressurized projection fluid streams of said entangling fluid from said plurality of projection fluid jets in a direction from said first surface of said support layer towards said projection forming surface to cause a) a first plurality of said fibers in said projection web in a vicinity of said forming holes in said projection forming surface to be directed into said forming holes to form a plurality of projections extending outwardly from said outer surface of said projection web, and b) a second plurality of said fibers in said projection web to become entangled with said support layer to form a laminate web, and removing said laminate web from said projection forming surface.
