Abstract:
A process for continuously producing a multi-layer feminine hygienic pad comprising a plurality of long sheets of a thermoplastic resin as a backing sheet, a plurality of long sheets of a porous film of a thermoplastic resin, and a plurality of sheets of a fluid-absorbing macromolecular compound, the process which comprises:(a) continuously laying one of the long sheets of a thermoplastic resin as a backing sheet having a sheet of a fluid-absorbing macromolecular compound being disposed thereon on a surface of one of the long sheets of a porous film of a thermoplastic resin so that the sheet of a fluid-absorbing macromolecular compound is disposed between the long sheets, pressing together side edge portions of the long sheets which have been laid together with a pressure-sensitive adhesive being disposed between the side edge portions of the long sheets to prepare a temporarily attached laminate sheet,(b) laying a plurality of the temporarily attached laminate sheets on top of each other,(c) heat sealing or melt cutting side edge portions of the temporarily attached laminate sheets to form an intermediate melt adhesion between the long sheets in a temporarily attached laminate sheet and to heat seal a long sheet of a thermoplastic resin as a backing sheet in one laminate sheet to a long sheet of a porous film of a thermoplastic resin in another laminate sheet disposed directly adjacent thereto and to heat seal a long sheet of a porous film of a thermoplastic resin in one laminate sheet to a directly adjacent long sheet of a thermoplastic resin as a backing sheet in another laminate sheet, and(d) cutting the thus prepared laminate to a prescribed length.
