Method and apparatus for manufacturing elastic leg disposable diapers

摘要

A method and apparatus for elasticizing the leg areas of disposable diapers is disclosed. A continuously moving elastic ribbon is attached to a continuously moving web at spaced apart locations along the length of the web corresponding to the leg areas of a finished diaper. The web is moved over an arcuate surface and the portion of the ribbon that is not attached to the web is drawn through a gap in the surface so that the unattached ribbon portion separates from the web and travels a shorter path than the web. While the web and unattached ribbon portion are separated, the unattached ribbon portion is cut so that only the ribbon portion attached to the web will have an elasticization effect on the finished diapers.
