Equipment and processes for the application of atomized fluid to a web substrate

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.
