    Abstract: Embossing method, and material made by the method, including at least a pair of embossing rolls having unmatched embossing patterns engraved independently from each other, and having enlarged sidewall clearances between adjacent, inter-engaged protrusions and recessions of the embossing patterns. The sidewall clearances can range from about 0.050mm to about 1.27 mm. The width of the protrusions can be greater than about 0.050mm. The peripheral surface of at least one of the embossing rolls can comprise a metal, a plastic, a ceramic, or a rubber. Also disclosed is an embossed web material capable of being used as a wrap material for food products, made by the above process.

    Abstract: The invention concerns a method for making a sheet of paper comprising at least two crimped cotton-wool-like cellulose plies (20, 40). It consists in: unwinding a first ply (20) in the form of a strip from a reel, embossing it on an embossing unit (10, 12) and forming protuberances at its surface, unwinding a second ply (40) in the form of a strip from a reel, guiding it downstream of the embossing unit (10, 12), superposing the two strips, with their protuberances facing inwards, and in applying a linking means (14, 16) so as to make the two strips integral with each other. Said method is characterised in that immediately upstream of said linking means (14, 16), a tension regulating means (18) is applied in the machine direction on one of the strips, such that the two strips have the same elastic deformation in the machine direction when the linking means is applied. The invention also concerns a product obtained by said method.
