Abstract
Abstract A process is provided for making a panty liner type of feminine napkin having an absorbent pad and a fluid permeable cover which is coterminous with the absorbent pad at each of the longitudinal ends. The process involves adhering the wrap to the pad with a water-based emulsion adhesive, selectively moistening the pad and compressing the coterminous longitudinal ends.

Claim 1
Independent Claim
151 words
A process for eliminating the delamination of the ends of a sanitary napkin having a fluid impervious baffle, an absorbent pad and a fluid permeable wrap said absorbent pad and said cover being coterminous and adhesively attached by a water soluble adhesive comprising: (a) folding said wrap and said pad along its longitudinal axis to produce a double thickness of said absorbent pad with said wrap surrounding said folded pad and the longitudinal edges of the wrapped pad being closely adjacent each other; (b) attaching said baffle to said wrapped pad over said longitudinal edge, said baffle being coterminous with said folded wrapped pad so that each end of the napkin has a coterminous folded layer of said absorbent pad and wrap and the end of said baffle; (c) moistening each of said ends; (d) applying a water based emulsion adhesive to said ends; (e) subjecting said ends to compressive force.
