  • Two-ply paper products with either nested or foot-to-foot embossments and method of making
    Patent number: 6261666
    Abstract: A method of producing a paper product which is formed from a pair of embossed webs enables the embossments to be arranged in either a nested or a foot-to-foot configuration. An embossing pattern has a machine direction and a cross-machine direction and is formed by a plurality of embossments. Adjacent embossments are spaced from each other in either or both of the machine direction and the cross-machine direction by an amount which exceeds the dimension of the embossments in that direction. A pair of embossing rolls are engraved with the same embossing pattern. When it is desired to produce foot-to-foot embossments, the embossing rolls are rotatably mounted so that the embossments on each roll are aligned. When it is desired to produce nested embossments, the embossing rolls are rotatably mounted so that the embossments on each of the rolls are positioned between the embossments on the other roll.
