Abstract
The present invention is directed to an embossed ply suitable for use in a multi-ply, embossed paper. The embossed ply has bosses of two different depths wherein the bosses having a greater depth or the "big bosses" alternate with the more shallow bosses or "small bosses". When the embossed ply is used to form a multi-ply paper, the small bosses are arranged in a tip-to-tip relation with bosses in a second embossed ply, while the big bosses of the first ply are positioned to nest between the bosses of the second ply. Furthermore, a method and apparatus for manufacturing the embossed, multi-ply paper is described.
