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 web material having a first surface and a second surface opposed thereto is disclosed. The apparatus is provided with a fluid source disposed adjacent to the first surface of the web material and a receipt plenum disposed adjacent to the second surface of the web material. The receipt plenum provides a source of negative pressure to the second surface of the web material. A fluid disposed from the fluid source contacts the first surface of the web material and is caused to traverse therethrough by the source of negative pressure. A portion of the fluid contacting the first surface of the web material is contained by the receipt plenum.

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; a receipt plenum having an 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 said 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.
