2081916 9118137 PCTABS00008 A method and apparatus for forming a nonwoven pad (30) of fibrous material (28) is provided in which highly moisture-absorbent particles (36) and thermoplastic material are intermixed with the fibrous material throughout one or more predetermined portions of the thickness of the nonwoven pad while maintaining other portions of the thickness of the pad substantially free of highly moisture-absorbent particles and/or thermoplastic fiber material. The nonwoven pad is formed on one side of a conveyor (18) moving through a forming chamber (12) which has a duct (22) connected to a source of vacuum (24) operable to draw fibrous material injected into the chamber onto the conveyor. One dispenser (40) discharges the highly moisture-absorbent material at a predetermined location relative to the fibrous material being drawn onto the conveyor, and at least one other dispenser (56, 68, 83, 84) discharges the thermoplastic fiber material.
