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.

A fibrous structure. The structure may include a plurality of continuous or semi-continuous knuckles extending from portions of the surface of the fibrous structure in a parallel path, wherein the plurality of knuckles may be separated by adjacent continuous or semi-continuous pillows. Each knuckle may comprise a plurality of discrete pillows, the plurality of discrete pillows may be arranged in a spaced configuration along the path of each knuckle; alternatively, each pillow may comprise a plurality of discrete knuckles, the plurality of discrete knuckles may be arranged in a spaced configuration along the path of each pillow.

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.

Creped fibrous structures having pillows and knuckles, wherein the creped fibrous structures exhibit improved knuckle properties, such as Knuckle Roughness Ra, Knuckle Roughness Rq, and Knuckle Creping Frequency and methods for making same are provided.

A machine for dewatering and drying a paper, cardboard or other fibrous web, to which machine a fibrous stock suspension is fed which is formed at least partially from waste paper. The machine includes at least two press nips which are formed in each case by two press rolls, wherein a fibrous web runs through first press nip with a water absorbing dewatering belt on both sides. The fibrous web then runs through a second press nip with at least one other dewatering belt and a smooth impermeable transfer belt on both sides. A transfer belt transfers the fibrous web after second press nip to a belt in a downstream machine unit, e.g. dryer group. The dryer group allows the fibrous web to be guided in a serpentine manner alternatively over heated dryer cylinders and vacuum equipped guide rolls.

A fibrous structure. The structure may include a plurality of continuous or semi-continuous knuckles extending from portions of the surface of the fibrous structure in a parallel path, wherein the plurality of knuckles may be separated by adjacent continuous or semi-continuous pillows. Each knuckle may comprise a plurality of discrete pillows, the plurality of discrete pillows may be arranged in a spaced configuration along the path of each knuckle; alternatively, each pillow may comprise a plurality of discrete knuckles, the plurality of discrete knuckles may be arranged in a spaced configuration along the path of each pillow.

The invention relates to a press belt for a shoe press. A press belt (5) is an endless loop made of elastomeric material and its outer surface (11) is provided with several grooves (13) to remove water. On the outer surface (11) of the press belt, there is at least one section where the depths (GD) of adjacent drain grooves, from the outer surface, change constantly. The invention also relates to an arrangement in a long nip and to a method of manufacturing a press belt.

The invention relates to a press for a machine for producing a fibrous material web, including at least one press nip formed between a press roller and a counter press roller of the press for guiding through the fibrous material web in a dehydrating manner, and two band shaped covers, which are each guided by multiple guide rollers in continuous circulation, so as to run together through the press nip, so that the fibrous material web is guided through sandwiched between said covers, and then separated again at a separation point, in order to continue guiding the fibrous material web on the one cover and separate it from the other cover. One guide roller of the guide rollers arranged at the separation point is a suctioned guide roller of the one cover, to hold the fibrous material web on the one cover at the separation position.

A seamed felt for use in a machine for producing a tissue web has a single-layer or multilayer base structure and at least one layer of non-woven fibers. The base structure has a textile structure with MD threads which form seam loops at the two front edges of the base structure. The fabric can be made endless by connecting its front edges by way of a seam. The seam can be formed by interlocking the seam loops of the two front edges and introducing a push-in element. The MD threads wholly or predominantly have a diameter 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 corresponding machine and a method for producing a tissue web.
