Patent ID: 8013207

Claim:
A method of forming a composite web structure containing at least one layer of particulate material and at least one layer of fibrous material, said web structure being adapted for use as an absorbent structure in an absorbent article, the method comprising: depositing the at least one layer of fibrous material and the at least one layer of particulate material in consecutive steps on a moving foraminous support to form layers on top of each other, feeding an airborn stream of particulate material to an applicator chamber in a first flow direction at a high speed of about 25 m/s or higher, said applicator chamber having an outlet opening located adjacent to said foraminous support and that the airborn stream of particulate material when entering said applicator chamber is allowed to expand and to hit a wall portion in said applicator chamber which is oriented at an angle between about 90 and about 125° to said first flow direction, whereby the airborn stream of particulate material is forced to change flow direction to a second flow direction, resulting in a reduction of speed of the airborn stream of particulate material as it exits an outlet opening of the applicator chamber, wherein the airborn stream of particulate material that exits the outlet opening of the applicator chamber is directly deposited on the moving foraminous support.
