Abstract
Abstract An adhesively laminated creped tissue product, having particular usefulness as a dinner napkin, is formed from two creped tissue webs superposed with the lines of creping of each web substantially parallel to the lines of creping of the other, and patterned adhesive disposed between the webs. Each web is in a different condition of stress in the plane of the laminated product. The bonded webs may be formed into individual napkins embossed about their periphery, leaving a substantial unembossed area in the center.
