ABSTRACT A disposable product and a process for manufactur- ing the disposable product on a flexible conveyor. The dis- posable product has an absorbent core formed by sandwiching a corrugated tissue between two separate feeds of fluffed pulp. Upper and lower layers of wadding are provided, the lower wadding being first folded around the absorbent core longitudinally and then an upper wadding is laid on top. The upper and lower waddings are then roller crimped to- gether and die cut and shaped and turned ninety degrees. Thereafter, a water impervious sheet of material, such as polyethylene, is provided with a glue line on its edges and is fed across the top wadding and wrapped about the top wadding, the core, and partially overlying the lower wadding. A sheet of non-woven material is then wrapped about the assemb- ly and provided with a longitudinal strip or strips of pres- sure sensitive adhesive. A release paper is applied over the adhesive to protect it prior to use. The lower layer of fluffed pulp is embossed and printed to form coated recesses partially therethrough for accommodating and absorbing sub- stantial discharges of material at a rate faster than other- wise possible so as to prevent leakage. These recesses are formed by the embossing and the coating is selected so that the recesses are stabilized. The material beneath the recesses are substantially compressed.
