An industrial fabric/belt including spiral coils shaped as a symbol for infinity or a lemniscate, i.e., infinity elements, are joined to each other with a pintle. A fabric element is configured as a continuous loop to form an industrial fabric employing a plurality of infinity coil elements.

A seam for joining fabric edges in which coils of seam elements shaped as a symbol for infinity or a lemniscate, that is, infinity elements, are joined to the fabric edges and the infinity elements are joined to each other with a pintle. A fabric element may be configured as a continuous loop to form an industrial fabric employing the infinity seam elements.

An industrial fabric is formed of several machine direction (MD) yarns and several cross machine direction (CMD) yarns. The MD-yarns are twisted relative their longitudinal axis so that the twisted yarns have sloped surfaces at least on a web side surface (P) of the textile. The textile is usable in paper machine, pulp machine or filtering machine.

A papermaking felt includes at least one base fabric composed of a MD yam material in the felt running direction (MD) and a CD yarn material in the felt crossing direction (CD) and having MD end regions and CD end regions, at least one of the MD end regions and the CD end regions are overlapped with each other, the entire overlapped portion is welded without removing a part or all of the MD yarn material or the CD yarn material in the overlapped portion, and when the average thickness of the welded portion of each base fabric is x (mm) and the average thickness of the material portion of each base fabric 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.

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.

The invention relates to an industrial fabric and its use. The industrial fabric (1) comprises several machine direction (MD) yarns (2, 2a, 2b) and several cross machine direction (CMD) yarns (3). The MD-yarns are twisted relative their longitudinal axis so that the twisted yams have sloped surfaces (4) at least on a web side surface (P) of the textile. The textile is usable in paper machine, pulp machine or filtering machine.

In a method for producing helical coils, in particular for coil screens, a filament is conveyed in a filament conveying direction through a first channel portion of a first rotation body, and subsequently conveyed through a second channel portion of a second rotation body which rotates synchronously with the first rotation body. The filament is subsequently wound around a protruding winding mandrel, such that a helical coil is produced from the filament by a continuous feed of the windings of the filament wound around the winding mandrel. A heated heating fluid flows with an excess pressure through the first channel portion and the second channel portion, arranged downstream, and in the process heats the filament conveyed through the first channel portion and subsequently through the second channel portion. The filament emerging from the second channel portion is deformed, using a deformation apparatus, prior to winding onto the winding mandrel.
