Abstract: A tissue paper (1) includes at least two plies (2,3,4). At least a first ply (2) of the plies includes pattern of areas (6), in which fibres protrude outside the plane of the ply in a direction towards the second of the at least two plies. A method for producing such a tissue paper is also disclosed.

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).

Abstract: In a process for laminating plies of tissue paper, at least two plies of tissue paper are combined and are embossed together in at least one embossing nip so that they are provided with substantially identical embossing patterns which consist of embossing protrusions. The embossed plies are then separated, and the separated plies are then displaced relatively to each other and are recombined. In the resultant recombined tissue, the maximum distance D in the displacement direction between an embossing protrusion of a first ply and an embossing protrusion of a second ply, which has been displaced relatively to said first ply, is set as a function of the height H of the embossing protrusions and the length L of the embossing protrusions in the displacement direction of the two plies, so that D is equal to the smaller one of the values of 12H and 14L.
