Generally, a pre-fastened adjustable pant-like disposable absorbent undergarment including a fully severed front body panel and method of manufacturing is disclosed. The method includes the steps of providing a moving web for use as a body panel and first forming a first cut on the moving web at a first cutting station to define a leading portion of the moving web and a trailing portion of the moving web connected at the first cut. The moving web then passes through an attachment assembly station to bridge the connected leading portion and trailing portion together with a fastener assembly that extends over the first cut. Finally, the moving web is then passed through a second cutting station to provide a second cut through both the moving web and fastener assembly and intersecting with the first cut to completely separate the leading portion and trailing portion of the moving web.
