Abstract:
A method for forming air-laid fibrous articles. The steps of the method can include providing a stream of loose air-entrained first fibers, providing a core pocket operatively related to the stream of loose air-entrained first fibers, the core pocket including a central foraminous forming surface and an edge foraminous forming surface, applying a negative pressure to one of the foraminous forming surfaces, applying a positive pressure to the other foraminous forming surface, depositing the first fibers on one of the foraminous forming surfaces, providing a stream of loose air-entrained second fibers, operatively relating the core pocket to the stream of loose air-entrained second fibers, applying a negative pressure to one of the foraminous forming surface, and depositing the second fibers on that foraminous forming surface.
