Abstract
A process is disclosed for creating air laid, high loft, non-woven, variable density web structures. The fiber manipulation and distribution necessary to produce a variable weight and density web is accomplished by creating variable, negative pressure regions across the surface of a condenser or other vacuum screen, which causes fibers to migrate toward areas of lower pressure. Also disclosed are embodiments of condenser and vacuum screens for producing such variable density web structures.
