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.

What is claimed is: 1. Apparatus for making a reinforced absorbent member including a fibrous material and a porous reinforcing web having inner and outer surfaces, said apparatus comprising: a forming chamber adapted to contain a fluent fibrous material; a forming surface moveable within the forming chamber along an arcuate path generally from an entrance of the forming chamber to an exit thereof, said forming surface being adapted to collect fibrous material thereon to form the absorbent member; a source of reinforcing web disposed generally exterior of the forming chamber; and a delivery tube having an inlet end open to the exterior of the forming chamber, a discharge end open to the interior of the forming chamber adjacent the forming surface, and a central passage extending between the inlet end and the discharge end, the delivery tube being arranged for receiving the reinforcing web from the source of reinforcing web into the central passage of the delivery tube at the inlet end thereof and guiding the web to the discharge end thereof for conveyance within the forming chamber toward the forming surface; said forming chamber having an opening through which the delivery tube is received into the forming chamber, said opening being disposed downstream of the forming chamber entrance generally in the direction of movement of the forming surface along said path. 2. Apparatus as set forth in claim 1 in combination with the reinforcing web wherein the delivery tube has a cross-sectional width in the range of about 0.1% to about 35% greater than the planar width of the reinforcing web. 3. Apparatus as set forth in claim 1 wherein the forming chamber is further adapted to receive superabsorbent material therein, the forming surface being further adapted to collect superabsorbent material thereon. 4. Apparatus for making a reinforced absorbent member including a fibrous material and a reinforcing web, said reinforcing web having inner and outer surfaces, said apparatus comprising: a forming chamber adapted to receive a fluent fibrous material therein; a forming surface moveable within the forming chamber and adapted to collect fibrous material thereon to form the absorbent member; a source of reinforcing web disposed generally exteriorly of the forming chamber; and a delivery tube having an inlet end open to the exterior of the forming chamber, a discharge end open to the interior of the forming chamber, 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 thereof extending within the interior of the forming chamber, said delivery tube being arranged for receiving the reinforcing web from the source of reinforcing web into the central passage of said tube at the inlet end thereof and guiding the web to the discharge end thereof for conveyance within the forming chamber toward the forming surface, the delivery tube being supported by the forming chamber, the inlet end and of the delivery tube being spaced outward from the forming chamber and the discharge end of the delivery tube being disposed within the forming chamber. 5. Apparatus for making a reinforced absorbent member including a fibrous material and a reinforcing web, said reinforcing web having inner and outer surfaces, said apparatus comprising: a forming chamber adapted to receive a fluent fibrous material therein; a forming surface moveable within the forming chamber and adapted to collect fibrous material thereon to form the absorbent member; a source of reinforcing web disposed generally exteriorly of the forming chamber; and a delivery tube having an inlet end spaced outward from the forming chamber and open to the exterior of the forming chamber, a discharge end open to the interior of the forming chamber adjacent the forming surface, 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 thereof extending within the interior of the forming chamber, said delivery tube being arranged for receiving the reinforcing web from the source of reinforcing web into the central passage of said tube at the inlet end thereof and guiding the web to the discharge end thereof for conveyance within the forming chamber toward the forming surface. 6. Apparatus for making a reinforced absorbent member including a fibrous material and a reinforcing web, said reinforcing web having inner and outer surfaces, said apparatus comprising: a forming chamber adapted to receive a fluent fibrous material therein; a forming surface moveable within the forming chamber and adapted to collect fibrous material thereon to form the absorbent member; a source of reinforcing web disposed generally exteriorly of the forming chamber; and a delivery tube having an inlet end spaced outward from the forming chamber and open to the exterior of the forming chamber, a discharge end open to the interior of the forming chamber, 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 thereof extending within the interior of the forming chamber, said delivery tube being arranged for receiving the reinforcing web from the source of reinforcing web into the central passage of said tube at the inlet end thereof and guiding the web to the discharge end thereof for conveyance within the forming chamber toward the forming surface, the delivery tube being disposed at an angle relative to the forming surface. 7. Apparatus for making a reinforced absorbent member including a fibrous material and a reinforcing web, said reinforcing web having inner and outer surfaces, said apparatus comprising: a forming chamber adapted to receive a fluent fibrous material therein; a forming surface moveable within the forming chamber and adapted to collect fibrous material thereon to form the absorbent member; a source of reinforcing web disposed generally exteriorly of the forming chamber; and a delivery tube having an inlet end spaced outward from the forming chamber and open to the exterior of the forming chamber, a discharge end open to the interior of the forming chamber, and a central passage extending between the inlet end and the discharge end, said delivery tube being arranged for receiving the reinforcing web from the source of reinforcing web into the central passage of said tube at the inlet end thereof and guiding the web to the discharge end thereof for conveyance within the forming chamber toward the forming surface, the delivery tube being sized and configured to permit passage of the web therethrough with the web in a generally planar configuration. 8. Apparatus for making a reinforced absorbent member including a fibrous material and a reinforcing web, said reinforcing web having inner and outer surfaces, said apparatus comprising: a forming chamber adapted to receive a fluent fibrous material therein; a forming surface moveable within the forming chamber and adapted to collect fibrous material thereon to form the absorbent member; a source of reinforcing web disposed generally exteriorly of the forming chamber; and an elongate delivery tube having an inlet end open to the exterior of the forming chamber, a discharge end open to the interior of the forming chamber adjacent the forming surface, 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 thereof extending within the interior of the forming chamber, said delivery tube being arranged for receiving the reinforcing web from the source of reinforcing web into the central passage of said tube at the inlet end thereof and guiding the web in a delivery direction to the discharge end thereof for conveyance within the forming chamber toward the forming surface, said delivery tube shielding the web against contact by fibrous material and having a generally aerodynamic profile in a cross section transverse to the delivery direction to minimize any disruption of fibrous material flow within the forming chamber.
