  • Process and apparatus for air forming an article having a plurality of reinforced superimposed fibrous layers
    Patent number: 7094373
    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.

  • Process and apparatus for air forming an article having a plurality of superimposed fibrous layers
    Patent number: 6982052
    Abstract: Process and apparatus for air forming an article having a plurality of superimposed fibrous layers. The layers are formed in substantially discrete forming chambers by depositing fibrous material on a forming surface which moves along an arcuate 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.

  • Multi-stage forming drum commutator
    Patent number: 6630096
    Abstract: A method and apparatus (20) for forming a fibrous web (50) includes a movable, foraminous forming surface (22) and a substantially stationary, vacuum-commutator duct system (24) which is located substantially subjacent the forming surface (22). The vacuum-commutator duct system (24) has an entrance opening (26) that changes in configuration along a longitudinal dimension (30) of the entrance opening (26).
