<p>A method for attaching elastic ribbon to inelastic web in making disposable diapers. The method comprises feeding an elastic ribbon to an assembly station in a stretched condition; applying adhesive intermittently on said elastic ribbon at predetermined intervals along the length of said ribbon while said stretched elastic ribbon is being fed to said assembly station; feeding first and second webs of substantially inelastic material to said assembly station; adhering the stretched elastic ribbon to said first web at said assembly station in those discrete areas of the ribbon that have adhesive applied thereto; applying bands of adhesive to one of said webs while said webs are being fed to said assembly station, said bands being registered such that they will ultimately lie outside the area occupied by the elastic ribbon adhered to said first web; adhering said second web to said first web at said assembly station in the areas of the bands of adhesive; maintaining said elastic ribbon in a stretched condition at least until said adhesive on said ribbon sets up; cutting said webs transversely along a line severing said elastic ribbon in a portion of its length which is not adhered to said first web; and allowing the severed unadhered ends of said elastic ribbon to relax and contract to their unstretched length, whereby the presence of the unadhered ends does not interfere with the performance of either the webs or the adhered elastic ribbon after converting the assemblage into a discrete elasticized article.</p> |
