The present invention relates to a technique for producing an absorbent article. More particularly, the invention relates to a method and apparatus for forming an absorbent article having a first superabsorbent-containing stratum, and at least a second superabsorbent-containing stratum. A method and apparatus for forming an article () includes a moving of a forming surface () through an operative forming chamber () along a forming path length (). A first fibrous stratum () of fiber material () can be deposited onto the forming surface (), and the first fibrous stratum () can have a first stratum thickness (). A first quantity of a first superabsorbent material () can be directed to form a selected combination with the first fibrous material to provide a first superabsorbent-containing stratum. A second fibrous stratum () of fibrous material can be deposited to overlie the first fibrous stratum (), and the second fibrous stratum () can have a second stratum thickness (). A second superabsorbent material () can be directed to form a selected combination with the second fibrous material to provide a second superabsorbent-containing stratum.
