A machine for producing a fibrous web, such as a tissue web, has pressing device with a pressing element and a counter-element with a closed surface for forming a pressure nip. A water-absorbing belt with a web side and an opposite pressing element side is guided together with the fibrous web through the pressure nip and the fibrous web is separated at the end of the pressure nip from the web side of the water-absorbing belt and runs further with the counter-element. The water-absorbing belt has at least a first ply and a second ply, and, as viewed in the thickness direction of the water-absorbing belt, a layer in or on the belt half which faces the pressing element, which layer has a higher specific throughflow resistance than the first ply and/or the second ply.

A functional belt has a foam layer and at least one further functional layer. The foam layer and the further functional layer are joined to one another by laser transmission welding, in particular by NIR laser transmission welding. A method for producing a functional belt includes the following method steps: providing a compressible foam layer; providing a further functional layer bringing together the foam layer and the further functional layer and joining the compressible foam layer to the further functional layer by laser transmission welding, in particular by means of NIR laser transmission welding. A technical textile, in particular a fabric for use in a machine for the production or processing of a fibrous material web, preferably press felt of a paper machine, a sealing band or a textile-reinforced insulation material, includes, or is made of, such a functional belt.

A fabric or belt for a papermaking machine including a first layer that defines a web contacting surface and a second layer that supports the first layer. The first layer is made of extruded polymer and includes a plurality of first elements aligned in a first direction, a plurality of second elements aligned in a second direction and extending over the plurality of first elements, and a plurality of open portions defined by the plurality of first and second elements. The second layer is made of woven fabric. The first layer is bonded to the second layer so that the first layer extends only partially through the second layer and an interface formed between the first and second layers includes bonded and unbonded portions and airflow channels that extend in a plane parallel to the first and second layers.

A fabric, in particular a press felt, is provided for use in a press section of a machine for producing a fiber web such as a paper, cardboard, or tissue web. The fabric is formed of multiple strips which are arranged adjacent one another and extend substantially parallel to one another in a machine direction. The strips together form a width of the fabric in the machine transverse direction. Each strip is designed as a double-layered sheet material. Strips arranged adjacently in respective pairs are connected by way of a connecting strip. A part of the width of each of the connecting strips extends in the machine transverse direction into the two adjacent strips. The strips are connected to the connecting strips.

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 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.

A clothing for a machine for producing a fibrous web, especially a paper, cardboard, tissue or cellulose pulp web. The clothing has a basic structure with a top side and a running side as well as a nonwoven support at least on one side. The nonwoven support has a functional zone, which extends over more than 50 μm in the thickness direction of the clothing and which includes a first portion and a second portion of nonwoven fibers. The nonwoven fibers of the first portion are formed of, or include, a polyurethane, especially a thermoplastic polyurethane, while the nonwoven fibers of the second portion are a polymer material not including a polyurethane. The first portion makes up between 10 wt. % and 60 wt. %, of the functional zone. There is also described a method for production and a suitable nonwoven fabric.

An endless-woven dryer fabric for a papermaking machine includes: a plurality of upper warp yarns; a plurality of lower warp yarns; and a plurality of weft yarns interwoven with the plurality of upper and lower warp yarns in a series of repeat units. Each weft yarn includes upper and lower portions, the upper portions interwoven with the upper warp yarns, and the lower portions interwoven with the lower warp yarns. The upper portion of each weft yarn includes a first seam loop and the lower portion of each weft yarn includes a second seam loop. The first and second seam loops of the weft yarns are interdigitated to form a seam, the seam receiving a pintle so that the fabric forms an endless loop.

A woven fabric has warp threads and weft threads that are interwoven for configuring a textile structure. The woven fabric has a thickness direction as well as a warp direction and a weft direction. The warp threads and/or the weft threads in the thickness direction have a wave-shaped profile. At least some, preferably all, weft threads have a wave-shaped profile in the warp direction, and/or at least some, preferably all, warp threads have a wave-shaped profile in the weft direction. Moreover, a technical textile is formed from such a woven fabric.
