The web is printed with at least one printing pattern which is in register with the glue pattern. The multi-ply web is produced by bringing a first ply in contact with a patterned glue transfer roll, transferring glue to the first ply in a glue pattern, a second ply is brought in contact with the glue applied side of the first ply in a press nip between a patterned lamination roll and an impression roll, the glue transfer roll and the lamination roll being in register with each other and having corresponding patterns.

Abstract: Apparatus for embossing a multi-ply paper product, includes at least one background embossing unit, for embossing at least one ply of the multi-ply paper product and at least one decoration embossing unit for embossing the at least one ply downstream of the background embossing unit, as seen in the direction of processing, the decoration embossing unit having a decoration embossing roll and a decoration backing roll. The decoration embossing roll of the decoration embossing unit has an engraving depth larger than 1.5 mm. By this arrangement, an increased bulk of the produced multi-ply paper product can be achieved, the decoration embossing having sharp edges, which in turn leads to an improved application of dye, if dyed glue is used for laminating the plies together. To strengthen this fact, it is preferable that the decoration backing roll has a hardness larger than 60 Shore (A).
