Abstract:

Process and apparatus for air forming an article having a plurality of superimposed fibrous layers. The layers are formed in substantially discrete forming chambers by depositing fibrous material on a forming surface which moves along an arcuate path through the chambers. A first layer is air-formed on the forming surface as the surface moves through the first forming chamber and a second layer is air-formed over the first layer as the surface moves through the second forming chamber.

Abstract:

A process and apparatus for air forming an article having a plurality of superimposed reinforced fibrous layers. The layers are formed in substantially discrete forming chambers by depositing fibrous materials on a forming surface which moves along a forming path through the chambers. A first layer is air-formed on the forming surface as the surface moves through the first forming chamber and a second layer is air-formed over the first layer as the surface moves through the second forming chamber. A reinforcing web is embedded in the article during the air-forming process.

International Classification:

A61F 13/15
A61F 13/20

US Classification:

604367, 604378

Abstract:

An absorbent structure can include a matrix of fibers, wherein the matrix is reinforced with a reinforcing member, such as scrim. Preferably, the scrim is secured to the fibrous matrix by entanglement of fibers with the scrim and entanglement of fibers in the matrix from opposite sides of the scrim with each other. The scrim layer can be restricted to a longitudinally extending, medial region of the absorbent. In a particular arrangement, the scrim has a cross-directional width dimension which is less than a narrowest width dimension of the fibrous matrix. The scrim can be located between two, opposed, major surfaces of the fibrous matrix.

International Classification:

D01G 1300

US Classification:

19145

Abstract:

A method and apparatus for depositing particulate material (30, 36) in an airlaid fibrous web (94) includes a moving of a forming surface (22) through a forming chamber (24), and a laying of a fibrous material (96) onto the forming surface to form the fibrous web. The particulate material is delivered into the forming chamber with an arcuate curved nozzle (86) which is positioned within the forming chamber at a location spaced from the forming surface.
