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.
