A process for manufacturing a multi-ply web material is disclosed. The process has the steps of: providing an embossing roll having first, second, and third nips disposed about a periphery thereof; providing a first web material; embossing the first web material in the first nip to produce an embossed first web material having embossed portions associated therewith; applying an adhesive to at least some of the embossed portions of the embossed first web material; joining the embossed first web material to a second web material in a face-to-face relationship in the second nip so that the embossed portions of the embossed first web material are contactingly engaged with corresponding portions of the second web material; and, embossing both the embossed first web material and the second web material in the third nip to produce the embossed multi-ply web material.
