摘要： A press felt is provided including a non-woven base fabric material formed of a first fabric structure, with the first fabric structure including an array of MD yarns connected with at least one layer of a hot melt adhesive web material and at least one layer of a non-woven backing. The non-woven backing includes a layer of a first yarn system and a layer of a second yarn system oriented transverse to the first yarn system. At least one of the first and second yarn systems includes a low melt temperature adhesive that is heat activated and binds the first and second yarn systems together. The nonwoven base fabric material has an MD length and CD width and is arranged in two superimposed layers joined by the MD oriented yarns at CD oriented fold regions at each of two opposing ends thereof.

摘要： The present invention provides for manufacturing processes of structuring fabrics that contain a web contacting layer with seams that do not cause defects in the sheet that can result in sheet breaks during the paper machine process. Structuring fabrics with a web contacting layer that can have damaged sections replaced rather than replacing the entire structuring fabric, which is costly and time consuming, are also provided. Additionally, a process for manufacturing the web contacting layer by laying down polymers of specific material properties in an additive manner under computer control (3-D printing) is provided.

摘要： An industrial textile for use in a fibrous web forming and/or processing machine has a transversal edge section which can be joined together to render the textile endless. MD-yarns are interwoven with CD-yarns. At least two adjacent MD-yarns form a group, the MD-yarns of each MD-yarn group weaving side-by-side the same weave path with the CD-yarns. Each of the MD-yarn groups has adjacent first and second MD-yarns. The first MD-yarn of a MD-yarn group is non-adjacent the first MD-yarn of an adjacent MD-yarn group and the second MD-yarn of said MD-yarn group is non-adjacent the second MD-yarn of the adjacent MD-yarn group. At each transversal edge section the first MD-yarn of a first MD-yarn group forms a first loop and weaves back into the weave path of the first MD-yarn of a second MD-yarn group. The second MD-yarn group is adjacent the first MD-yarn group.

摘要： A fabric for a machine that produces a fiber web, especially a paper-, board-, tissue- or pulp web. The fabric has a flat woven base material having a top side and a bottom side, two terminal ends separated in a machine direction. Folds are formed in the flat woven base material separated in the machine direction, whereby the two terminal ends are located under the bottom side surface. The two terminal ends are arranged adjacent to each other or they overlap each other. Seam loops are located at the folds. The novel fabric has at least one woven component, that is a multi-layer weave, especially a two-layer weave.

摘要： A seaming element for an industrial textile and a method of manufacture. The seaming element comprises an elongate body folded along its length at a folded connection region comprising a plurality of channeled protrusions securable to corresponding channeled protrusions of a complementary seaming element affixed to an opposing seamable edge. First and second body members extend from respective edges of the folded connection region, each body member being directly securable to the first seamable edge. At least one of the body members comprises a longitudinal profiled region proximate and substantially parallel to a free edge of the respective member. The method includes providing an array of apertures to form the channeled protrusions, and the profiled region is formed in a progressive roll forming process. The seaming element enables improved consistency and reliability of bonding of the element to the textile by laser welding, adhesives or other methods.

摘要： A seamed press felt formed from a base fabric material including MD yarns arranged in two superimposed layers joined by the MD yarns at CD folds at opposing ends thereof to form a continuous unbroken tube-like structure. The MD yarns form loops at the folds to define a pintle channel. A generally planar yarn assembly including an array of polymeric yarns bonded to an elastic carrier material that is extensible by at least 1% is located inside the base fabric with the yarns of the array oriented in the CD. A high surface contact area material is bonded to the elastic carrier material at both exterior MD ends adjacent to the MD loops at the folds. Each of the MD ends is anchored in a fixed position adjacent to the loops at the folds. A pintle extends through the channel defined by intermeshing the loops from the opposing ends.
