ABSTRACT:
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. Further disposed are particular configurations of rollers with radially displaceable surfaces.
