摘要： A seamed press felt formed from a base fabric having a CD width and an MD length with two opposing MD ends that are joined to form a continuous belt. MD oriented yarns form uniform loops at the two opposing MD ends that are interdigitated to define a pintle channel extending across the CD width. CD oriented yarns are connected to the MD oriented yarns, in a woven or non-woven construction. Loop open spaces are located within the loops on each of the two opposing MD ends in a seam region, with the loop open spaces being defined between a last one of the CD yarns at each of the two opposing MD ends and the pintle channel. At least one CD monofilament support yarn is located in the loop open spaces on each of the two opposing MD ends. The at least one CD monofilament support yarn has a diameter that is at least 1.6 times a diameter of the CD oriented yarns. A pintle extends through the pintle channel to form a seam.

摘要： A fabric for a paper or pulp technology has a longitudinal direction (MD) and a cross direction (CMD), and a first surface (FS) and a second surface (SS) in a fabric thickness direction (TD). The fabric (1) extends in the cross direction (CMD) from a first edge (FG) to a second edge (SG). The fabric (1) has an adaptable medium comprising at least one sensor. The adaptable medium is a deformable structure that adapts to the fabric where it is inserted and may be a string or a sheet configured to detect temperature, temperature profile, wear, volatile organic compounds (VOC), humidity, pH, microbial level, organic and inorganic material content, dirt content, flow rate and flow velocity field, or pressure in a nip. The invention also relates to a method for manufacturing a fabric for a paper or pulp technology.

摘要： 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.

摘要： A seam connecting fabric edges is formed by surrounding a first fabric edge with a first plush material strip suitable for the attachment of a hooked material. The first plush material strip defines a first front surface and a first rear surface. A second fabric edge is surrounded with a second plush material strip having a second front surface and a second rear surface. A single strip of a hooked material is deployed behind the first rear surface and the second rear surface. Then, with the first surrounded edge substantially in contact with the second surrounded edge, a force is applied to engage hooks of the single strip of hooked material with said first rear surface and said second rear surface.

摘要： A covering is particularly suited for use in a machine for producing and/or finishing a paper, cardboard, tissue or pulp web. The covering has a basic structure formed as a part of a flat woven material, which flat woven material is designed as a woven material by interlacing warp threads and weft threads. The portion of the flat woven material has a plurality of sections that are formed integrally with each other, with at least one property of one of the sections differing from the respective property of at least one adjacent section.

摘要： The present invention is directed to forming fabrics. The forming fabrics may include a series of repeat units. Each of the repeat units may include a set of binding warp yarns including a first set of binding warp yarns and a second set of binding warp yarns, wherein a binding warp yarn from the first set is paired with a binding warp yarn from the second set; a set of spring warp yarns, wherein each spring warp yarn is between a first pair of binding warp yarns and a second pair of binding warp yarns; a set of top weft yarns including odd and even top weft yarns, wherein the top weft yarns interweave with the binding warp yarns and the spring warp yarns to form a top fabric layer, wherein the spring warp yarns interweave only with the top weft yarns; a set of bottom weft yarns; and a set of bottom warp yarns, the bottom warp yarns interwoven with the bottom weft yarns to form a bottom fabric layer. The binding warp yarns from the first and second set and the spring warp yarns interweave with the top weft yarns to relatively form a plain weave pattern in defined zones such that (a) the first set of binding warp yarns only pass over even top weft yarns; (b) the second set of binding warp yarns only pass over odd top weft yarns; (c) the first binding warp yarn in the pair is offset from the second binding warp yarn in the pair by at least three top weft yarns to create an overlap in the warp path of the pair of binding warp yarns; and (d) each spring warp yarn passes over even and odd top weft yarns. The binding warp yarns from the first and second set and the bottom warp yarn interweave with the bottom weft yarns.

摘要： A seam for joining together the ends of woven fabric to form an endless belt is particularly suitable for joining the ends of woven synthetic dryer fabrics as used in the dryer section of paper making machines and is particularly applicable to joining the ends of those dryer fabrics in at least the machine direction of the fabric. A papermaking fabric comprising a woven fabric body having opposing ends, said fabric body having a system of MD-yarns interwoven with a system of CD yarns. The MD-yarns include first pairs of MD-yarns, second pairs of MD-yarns and third pairs of MD-yarns and the first and the second pairs of MD-yarns form two seam loops, while the third MD-yarns forms the binder. The loops are at identical length to each other over the whole fabric width. Such seam construction reduces marking and increases the seam strength and seam abrasion resistance.
