A dryer fabric has a weft of cross machine direction yarns (6) and a first warp of first machine direction yarns (5) and a second warp of second machine direction yarns (9). The yarns of the first warp are arranged above the yarns of the second warp on a first surface (FS) side. The first warp has primary yarns (51) of PPS or PK yarns whose breaking load remains substantially stable within 15 days in conditions where RH=100%, T=125° C. and p=2.3 bar; and secondary yarns (52) of PET with breaking loads which substantially decrease under the same conditions. At least every second yarn of the first warp is a secondary yarn (52). The secondary yarns (52) may be two out of three or three out of four of the first machine direction yarns (5). PET reduces cost and adds elasticity to the dryer fabric.

[Problem to be solved] To provide a papermaking felt excellent in smoothness of a joined portion (no welded portion mark or base fabric mark is generated), and an efficient manufacturing method thereof.

[Solving means] A papermaking felt wherein, in at least one base fabric composed of a MD yarn material in the felt running direction (MD direction) and a CD yarn material in the felt crossing direction (CD direction) and having MD-direction end regions and CD-direction end regions, at least one of the MD-direction end regions and the CD-direction end regions are overlapped with each other, wherein said overlapped portion is welded without removing a part or all of the MD yarn material or the CD yarn material in said overlapped portion, and wherein, when the average thickness of the welded portion of each base fabric is x (mm) and the average thickness of each base fabric before welding is y (mm), the relationship between x and y of the at least one base fabric satisfies the following formula (1):

0.5≤x/y≤0.95   (1)

A web connection for a fabric of a machine for producing or processing a fibrous material web includes a first web end with first longitudinal thread ends, a second web end with second longitudinal thread ends, and at least one connection element which extends in the transverse direction of the resultant fabric. The connection element has an upper face and a lower face, and the first longitudinal thread ends and the second longitudinal thread ends solely contact and bond to the upper face of the connection element, in particular the thread ends are welded thereto. The fabric with a paper side and a running side. The fabric has at least one first web layer with at least one such web connection which is arranged such that the lower face of the at least one connection element is oriented in the direction of the running side of the fabric.

A structured tissue belt assembly including a supporting layer, a non-woven web contacting layer, and one or more laser welds that attach the bottom surface of the web contacting layer to the top surface of the supporting layer. The structured tissue belt assembly allows for air flow in x, y and z directions. In exemplary embodiments, the structured tissue belt assembly has an embedment distance between the supporting layer and the web contacting layer of 0.05 mm to 0.60 mm and a peel force between the web contacting layer and the supporting layer of at least 650 gf/inch.

A method of forming a fibrous web on a papermaking machine including the steps of depositing a dilute fiber slurry out of a headbox to a forming area comprising a forming surface made up of a structured fabric, wherein the structured fabric is supported by a breast roll and a forming roll, and the forming area is devoid of any additional fabrics or belts other than the structured fabric, draining the dilute fiber slurry through the structured fabric, and drying the fiber slurry.

A clothing, in particular a seam felt for a machine for producing a fibrous material web, in particular a paper, paperboard, tissue or pulp web, includes a base structure including or being formed of a two-layer laminate structure formed of one or more flat-woven fabrics. The laminate structure has MD threads which form seam loops at the two end sides of the base structure, and the two layers of the laminate structure are connected to one another by the seam loops. The clothing is made endless by connecting the end sides thereof by a seam. The seam is made by interengaging the seam loops of both end sides and introducing an insertion element. The diameter of the seam loops LD and the diameter of the associated MD threads MDYD have a ratio LD/MDYD of between 2.5 and 4, in particular between 2.7 and 3.6.
