A web of a first sheet material and a web of a second sheet material are laminated together by a process wherein the sheet materials are wound, in an interleaved relationship, upon a roller having a radially displaceable outer surface. The roller and webs and then subjected to heating and/or a low-pressure environment so as to complete the lamination. A body of adhesive material, such as a hot melt adhesive, may be interposed between the webs and the heating or low pressure environment can activate this adhesive.
