Press cover, use thereof, and press roll and shoe press
A press cover has at least one polymer layer in which a reinforcing structure is embedded. The reinforcing structure has at least one reinforcing thread as a longitudinal thread which runs in the longitudinal direction of the press cover. The at least one reinforcing thread itself is produced by interlacing a plurality of fibers or fiber bundles with one another. There is also described the use of such a press cover, as well as a press roll and a shoe press.

Method and a machine for of making tissue paper
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. The side of the texturing belt that contacts the fibrous web comprises a layer of a polymer material such that the polymer material will contact the fibrous web and cavities are formed in that surface of the texturing belt that comes into contact with the fibrous web.

FIBROUS BODY MANUFACTURING APPARATUS, FIBROUS BODY MANUFACTURING METHOD, GROUND SHEET, AND FUNCTIONAL SHEET
A fibrous body manufacturing apparatus includes a putting-out unit, a transportation unit, a deposition unit, and a pressing and heating unit. The putting-out unit puts a ground sheet out, with a functional member arranged on one side of a sheet. The transportation unit transports the ground sheet put out onto itself. The deposition unit lets fibers and a binder deposit on one side of the transported ground sheet, thereby forming a web thereon. The pressing and heating unit applies pressure and heat to the web.
