Abstract
A method for applying a foam composition to a paper web is provided. Specifically, a foam applicator is positioned adjacent to a surface of the web. The foam applicator defines an extrusion slot through which the foam composition is capable of flowing. In one embodiment, the extrusion slot is in communication with an air channel. The foam composition is optionally entrained with an air stream traveling through the air channel. The foam composition contacts at least one liquid-permeable partition (e.g., wire-mesh screen) to fragment gaseous bubbles contained therein.
Claims21
A method of applying a foam composition to a paper web having a first surface and an opposing second surface, said method comprising:
- positioning a foam applicator adjacent to said first surface of said web, said foam applicator defining an extrusion slot through which the foam composition is capable of flowing, said foam applicator further defining a dispensing slot through which the foam composition is capable of exiting said foam applicator;
- flowing the foam composition through said extrusion slot of said applicator to an air channel being in communication with an air supply which introduces a stream of air into the air channel;
- entraining said foamed composition in said air channel with said stream of air;
- contacting said foam composition with at least one liquid-permeable partition that is disposed within said foam applicator;
- and
- flowing said foam composition through said dispensing slot and onto said first surface of said paper web.
A method of applying a foam composition to a paper web having a first surface and an opposing second surface, said method comprising:
- positioning a foam applicator adjacent to said first surface of said web, said foam applicator defining an extrusion slot through which the foam composition is capable of flowing, said extrusion slot being in communication with an air channel in which at least one wire-mesh partition is disposed, said foam applicator further defining a dispensing slot through which the foam composition is capable of exiting said foam applicator;
- being in communication with an air supply which introduces a stream of air into the air channel;
- flowing the foam composition through said extrusion slot of said foam applicator;
- entraining said foamed composition in said air channel with said stream of air accelerating through said air channel;
- contacting said entrained foam composition with said wire-mesh partition;
- thereafter, flowing said foam composition through said dispensing slot and onto said first surface of said paper web.
