Abstract:
A method of forming a plurality of disposable undergarments, the method comprising:forming a continuous stream of a plurality of elongate undergarment cores in-line along a path of travel so that said undergarment cores have a lengthwise extent disposed along the path of travel;separating the stream of the plurality of undergarment cores into a plurality of individual elongate undergarment cores intermittently-spaced along a substantially in-line path of travel;orienting in-line each of the individual undergarment cores so that each lengthwise extent is disposed substantially transverse to the same substantially in-line path of travel;dividing a continuous sheet of non-woven material into a plurality of continuous strips;combining strips of elastic material with the plurality of continuous strips of non-woven material so as to form a pair of continuous strips of elastic waistband material;securing the pair of continuous strips of elastic waistband material extending along the substantially in-line path of travel to each of the plurality of individual undergarment cores so as to form a chain of a plurality of individual undergarments;folding each of the pair of continuous waistband strips;folding the cores of each of the plurality of undergarments of the chain;side folding the folded cores of the plurality of undergarments of the chain;ultrasonically sealing side peripheries of at least the waistband of each of the plurality of undergarments of the chain; andseparating the chain of the plurality of undergarments into individual undergarments.
