Abstract
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.
