Abstract:
A method of forming a web of fibrous media comprising: feeding first fibers in attenuated multiple fiber layers from a first spaced orifice zone in a first feed path to a first spaced longitudinally extending rotating collector zone in successive lower and upper fiber layers, said fibers having a first selected fiber size distribution when passed to said first collector zone to form a first fibrous mat having a first selected fiber size distribution thereon; feeding said first formed fibrous mat to at least a second similarly rotating collector zone spaced from said first rotating collector zone; feeding second fibers in attenuated multiple fiber layers from a second spaced orifice zone in a second feed path to said second collector zone spaced from said second orifice zone to form a second fibrous mat combined with said first fibrous mat fed to said second collector zone from said first collector zone, said second fibers having a second selected fiber size distribution and, feeding said combined fiber mat from said second collector source zone to a further mat forming zone.
