ABSTRACT A disposable product and a process for manufactu?- ing the disposable product on a flexible conveyor. The disposable product has an absorbent core formed by sand- wiching a corrugated tissue between two separate feeds of fluffed pulp. Upper and lower layers of wadding are pro- vided, 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 together 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 assembly and provided with a longitudinal strip or strips of pressue sensitive adhesive. A release paper is applied over the adhesive to protect it prior to use. The lower layer of fluffed pulp is provided with recesses partially therethrough for accommodating subst?ntial dis- charges of material at a rate faster than absorption is possible so as to prevent leakage. These recesses are formed by embossing so that the material beneath the recesses are substantially compressed.
