Abstract
The invention relates to a method of making tissue paper in a machine for making tissue paper and in which method a fibrous web is passed through at least one press nip together with a texturing belt. The texturing belt has a side that faces the fibrous web in the press nip and the surface of that side is a web contacting surface that is textured. The texturing belt can be selected such that the tissue paper that is manufactured obtains desired values for one or several parameters. The invention also relates to a machine for making tissue paper. The machine comprises a forming section, a drying cylinder, a press having a first press unit and a second press unit between which press units a nip is formed. The second press unit is preferably a shoe roll. The machine also comprises a drying cylinder which is arranged to be heated from the inside by hot steam and on which a fibrous web can be dried by heat. A texturing belt is arranged to run in a loop through the nip and to the drying cylinder such that a fibrous web can be carried by the texturing belt to the drying cylinder and transferred to the drying cylinder.
