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.
Claims25
An apparatus for depositing particulate material in an airlaid fibrous web, the apparatus comprising:
- a forming chamber;
- a forming surface which can be moved through said forming chamber, said forming surface configured to accumulate fibrous material thereon as the forming surface is moved through said forming chamber;
- a fiber source which can provide said fibrous material into said forming chamber for laying onto said forming surface to form said fibrous web;
- an arcuate curved nozzle which is positioned within said forming chamber at a location spaced from said forming surface, said curved nozzle having a radius of curvature of at least a minimum of about 2.54 cm and a curved arc length of at least a minimum of about 3 cm, and said curved nozzle configured to include a plurality of outlet apertures in an array located in a radially outboard wall of said curved nozzle to deliver said particulate material into said forming chamber.
A method for depositing particulate material in an airlaid fibrous web, comprising a positioning of an arcuate curved nozzle within a forming chamber at a location spaced from a movable forming surface to deliver said particulate material onto fibrous material which has accumulated on said forming surface;
- providing said curved nozzle with a radius of curvature of at least a minimum of about 2.54 cm and a curved arc length of at least a minimum of about 3 cm;
- and configuring said curved nozzle to include a plurality of outlet apertures in an array located in a radially outboard wall of said curved nozzle.
