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.
