发明名称 Equipment and processes for the application of atomized fluid to a web substrate
摘要 An apparatus for the application of atomized fluid to a permeable web material is disclosed. The apparatus has a fluid source and a receipt plenum. The fluid source is disposed in proximate fluid contact with the first surface of the web material. The fluid source has a positively pressured permeable roll having atomized fluid and at least one aperture disposed therein. The apertures provide fluid communication between an inner portion of the roll and a surface thereof. The fluid is disposable from the inner portion to the surface through the apertures into contacting engagement with the permeable web material. The receipt plenum has an opening disposed adjacent to the second surface of the web material that provides a source of negative pressure to the second surface of the web material that causes the fluid to traverse through the web.

主权项 1. An apparatus for the application of atomized fluid to a permeable web material having a first surface, a second surface opposed thereto, a machine direction, and a cross-machine direction orthogonal and co-planar thereto, the apparatus comprising: a fluid source disposed in proximate fluid contact with said first surface of said web material, said fluid source comprising a positively pressured permeable roll, said positively pressured permeable roll having apertures disposed therein, said apertures providing fluid communication between an inner portion of said positively pressured permeable roll and a surface thereof, said positively pressured permeable roll having said atomized fluid disposed therein, said atomized fluid being disposable from said inner portion to said surface through said apertures and into contacting engagement with said permeable web material when said permeable web material is at least proximate to said surface; a receipt plenum having at least one opening disposed adjacent said second surface of said web material, said receipt plenum providing a source of negative pressure to said second surface of said web material through a portion of said at least one opening; wherein said atomized fluid disposed from said fluid source contacts said first surface of said permeable web material and is caused to traverse therethrough by said source of negative pressure; and, wherein a portion of said atomized fluid contacting said first surface of said web material is contained by said receipt plenum.
