Abstract
A method of utilizing a single engraved embossing roll to emboss different expanses of material with different patterns. The single engraved embossing roll has at least two projections projecting therefrom. A first of the projections projects to a greater height from the roll than a second of the projections. In another aspect, the invention encompasses an apparatus for embossing different expanses of material with different patterns. The apparatus includes an engraved surface having at least two projections projecting therefrom. A first of the projections projects to a greater height than a second of the projections. The apparatus also includes a backing surface configured to receive the projections of the engraved surface. The backing surface and engraved surface are together configured to receive an expanse of material between them. The apparatus further includes a displacement mechanism configured to move at least one of the engraved surface and the backing surface relative to the other of the engraved surface and the backing surface.
