Method for making air-laid structures

A method for forming air-laid fibrous articles. The method includes the steps of providing a stream of loose air-entrained fibers, providing a core pocket assembly comprising a central foraminous forming surface and an edge foraminous forming surface, applying a first pressure to the central foramin...

Zusammenfassung:A method for forming air-laid fibrous articles. The method includes the steps of providing a stream of loose air-entrained fibers, providing a core pocket assembly comprising a central foraminous forming surface and an edge foraminous forming surface, applying a first pressure to the central foraminous forming surface, applying a second pressure to the edge foraminous forming surface wherein the second pressure applied to the edge foraminous forming surface differs from the first pressure applied to the central foraminous forming surface, depositing a portion of the stream of loose air-entrained fibers on the central foraminous forming surface, and depositing a portion of the stream of loose air-entrained fibers on the edge foraminous forming surface.
