  • Patent number: 7568900
    Abstract: Apparatus for making a reinforced absorbent member includes a forming chamber adapted to contain a fluent fibrous material. A forming surface is moveable within the forming chamber along an arcuate path generally from an entrance of the forming chamber to an exit thereof. The forming surface is adapted to collect fibrous material thereon to form the absorbent member. A source of reinforcing web is disposed generally exterior of the forming chamber. The forming chamber has an opening through which the reinforcing web is received into the forming chamber for subsequent conveyance within the forming chamber toward the forming surface. The opening is disposed downstream of the forming chamber entrance generally in the direction of movement of the forming surface along the path.

  • Patent number: 7204682
    Abstract: Apparatus for making a reinforced fibrous absorbent member includes a forming chamber adapted to receive a fluent fibrous material and a forming surface moveable within the forming chamber and adapted to collect fibrous material to form the absorbent member. A source of reinforcing web is disposed exteriorly of the forming chamber. A delivery tube has an inlet end open to the forming chamber exterior, a discharge end open to the forming chamber interior, and a central passage extending between the inlet end and the discharge end. At least a portion of the delivery tube adjacent the discharge end extends within the forming chamber interior. The delivery tube is arranged for receiving the reinforcing web from the source of reinforcing web into the central passage of the tube at the inlet end and for guiding the web to the discharge end for conveyance within the forming chamber toward the forming surface.

  • Patent number: 6989118
    Abstract: In a process and apparatus for making a reinforced fibrous absorbent member, fibrous material is collected on a forming surface to at least partially form the absorbent member. Fibrous material is entangled with a reinforcing web which is overlaid on at least a portion of the partially formed absorbent member. Additional fibrous material is collected on the forming surface to further form the absorbent member whereby at least a portion of the fibrous material forming the absorbent member becomes entangled with at least one of the reinforcing web and the fibrous material entangled with the reinforcing web to secure the reinforcing web within the absorbent member.
