  • Method for applying binding agents to fibrous webs
    Patent number: 4385954
    Abstract: A method and system for applying a foamed binding agent to a fibrous web is disclosed. The invention is characterized by the use of an extruder having an upper lip extending 1/16 to 1/4 inch beyond the lower lip, and by the drawing of a vacuum beneath the applied foam, said characteristics being critical to the formation of a uniform foam layer atop the web. A second, more substantial vacuum is then applied beneath the web to essentially completely draw the binding agent into the web thereby providing substantial inter-fiber bonding.
