Abstract
Here is disclosed a method for manufacturing individual disposable underpants provided around a waist line and a pair of leg-holes with elastic members from two continuous webs and a plurality of continuous elastic members, characterized by that the webs are applied on predetermined locations with adhesive so that the elastic members can be reliably held on the webs although the elastic members must be forcibly curved when the elastic members are bonded between the webs with use of adhesive.
