摘要：An apparatus for forming a non-woven pad consisting of fibrous material inwhich highly moisture-absorbent particles are intermixed with the fibrous materialthroughout a predetermined portion of the thickness of the non-woven pad. The non-woven pad is formed atop a conveyor moving through a chamber which has a ductconnected to a source of vacuum operable to draw fibrous material injected into thechamber onto the conveyor. A spray gun or an extension thereof is positioned within thechamber relative to the fibrous material atop the conveyor, and is operated to dischargemoisture-absorbent material at a predetermined velocity, such that the moisture-absorbent material is intermixed with the fibrous material throughout preferably acenter layer of the thickness of the non-woven pad while forming boundary layers oneither side of the center layer which are substantially free of moisture- absorbentmaterial. The spray gun preferably operated intermittently to form spaced, sharplydefined areas along the length and width of the non- woven pad wherein each area hasmoisture-absorbent material interspersed throughout a portion of the thickness thereof.
