A device dewaters a wet-laid non-woven web formed from a fibrous suspension. The device has a multiplicity of dewatering strips which are disposed so as to be mutually spaced apart. Mutually neighboring dewatering strips conjointly delimit a dewatering gap for discharging liquid from the fibrous suspensions. The device further has at least three format slides which along the longitudinal direction of the respective dewatering gap are disposed or disposable so as to be distributed relative to one another and which partially obscure the dewatering gap in such a manner that any discharging of the liquid by way of the obscured part of the dewatering gap is prevented.

There is provided a sheet manufacturing apparatus including: an accumulation section that accumulates a material containing fibers by an air flow to form a web; a humidification section that applies moisture from one surface side of the web; and a pressurization section that pressurizes the humidified web to form a sheet, in which the pressurization section includes a first roller that comes into contact with one surface of the web and a second roller that comes into contact with the other surface of the web, and a surface of the first roller is harder than a surface of the second roller.

A fabric, in particular a felt, for use in a machine for producing a tissue web, has a base structure, which has a textile structure with MD threads, and at least one layer of nonwoven fibers. The MD threads predominantly or as a whole have a diameter ranging between 0.25 mm and 0.45 mm, in particular between 0.3 mm and 0.35 mm, and the thread density of the MD threads is more than 37%, in particular between 37% and 45%. There is also described a machine and a method for producing a tissue web using such a fabric.

The present invention relates to a method of making tissue paper in which a fibrous web (W) is formed in a forming section (2) and transferred to a Yankee drying cylinder (12) in a non-dewatering transfer nip (TN) formed between the Yankee drying cylinder (12) and a shoe roll (14). The Yankee drying cylinder (12) has a cylindrical outer surface (13) and it is arranged to be rotatable about an axis of rotation (A). The shoe roll (14) has a shoe (15) that is deformable such that it can adapt to the cylindrical outer surface (13) of the Yankee drying cylinder (12) and the shoe roll (14) also comprises a rotatable flexible jacket (16) that is arranged to run in a loop around the shoe (15). A structured carrier fabric (10) runs in a loop around the shoe roll and has land areas and void areas facing the fibrous web. The method comprises forming the transfer nip (TN) between the shoe (15) and the cylindrical outer surface (13) of the Yankee drying cylinder (12) and the length (L) of the transfer nip (TN) in the circumferential direction of the Yankee drying cylinder (12) is in the range of 30 mm -100 mm and the linear load in the transfer nip (TN) is in the range of 35 kN/m-120 kN/m. According to the invention the peak pressure in the transfer nip (TN) as defined by the linear load divided by the land area of the carrier fabric (10) lies in the range 2 MPa-8 MPa.
