  • Patent number: 6776952
    Abstract: An apparatus is provided for manufacturing a flexible sheet product having liquid absorbent qualities. The apparatus generally includes first and second competing vacuum systems pulling air in substantially opposite directions into first and second oppositely rotating screens, respectively. A molten polymer-based material, which is blown into the first and second competing vacuum systems, is pulled in substantially opposite directions onto the first and second oppositely rotating screens. The liquid polymer-based material fiberizes as it is being pulled apart by the competing vacuum systems creating a web of fibrous material which cures to develop the flexible sheet product having liquid absorbent qualities.
