Process for uniform cross-direction distribution of particulate material

A method for forming a substantially uniform distribution of particulate material in the cross-machine direction within a fibrous web, comprising the steps of:

• (a) providing a gas entrained supply stream of said particulate material;
• (b) transferring a selected quantity of said particulate material into a delivery gas stream to provide a flow of said particulate material through a delivery conduit and a delivery nozzle, including an end edge and having a circular shape including gaps on the end edge facing into a web forming chamber, into said web forming chamber;
• (c) providing a flow of a selected fibrous material into said web forming chamber;
• and,
• (d) receiving said fibrous material and said particulate material on a foraminous forming layer located within said forming chamber to produce said fibrous web which includes a substantially uniform distribution of said particulate material.

• (a) providing a gas entrained supply stream of said particulate material;
• (b) transferring a selected quantity of said particulate material into a delivery gas stream to provide a flow of said particulate material through a delivery conduit and a delivery nozzle, including an end edge and having a oval shape including gaps on the end edge facing into a web forming chamber, into a web forming chamber;
• (c) providing a flow of a selected fibrous material into said web forming chamber;
• and,
• (d) receiving said fibrous material and said particulate material on a foraminous forming layer located within said web forming chamber to produce said fibrous web which includes a substantially uniform distribution of said particulate material.
