Abstract:
A method for making a body waste disposable article having a body fluids absorbent means comprising a liquid-pervious topsheet, a liquid-impervious backsheet and a liquid-absorbent core disposed therebetween, a surrounding wall being defined by a portion of at least one of said topsheet and said backsheet extending outward beyond a peripheral edge of said absorbent means and folded back to partially cover a top surface of said absorbent means in proximity of said peripheral edge and thereby to leave an opening surrounded by said surrounding wall above a central zone of said absorbent means, and said surrounding wall being elastically stretchable and contractable along an edge of said opening, said method comprising the steps of:a. covering said core with said topsheet and said backsheet which are, in turn, bonded to each other along their portions extending outward beyond a peripheral edge of said core to obtain a laminate; b. bonding elastic members to any one of said topsheet and said backsheet with a rectilinear tension along transversely opposite edges of the topsheet or the backsheet extending in parallel to each other with said core lying therebetween; c. folding said laminate back onto itself with said topsheet lying inside so that said elastic members on said side edges may be placed upon each other; d. bonding respective halves of said laminate, which have been folded back onto itself, to each other along a pair imaginary lines intersecting said side edges and extending parallel to each other with said core lying therebetween; e. releasing said elastic members to contract after said step d.
