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.
