A device for connecting two or more pieces of fabric. The devices is formed as a bonding strip having a base and a plurality of spikes extending from the base. The bonding strip is formed of a material having a forming temperature that is lower than that of the fabric to be bonded. To bond the two or more pieces of fabric, the spikes are pushed through the fabric. The spikes are then formed at a temperature that is at least as high as the forming temperature of the bonding strip but lower than the forming temperature of the fabric. The forming can be performed so that the spikes bend over and press against the fabric. The spikes can be arranged on first and second rows along the bonding strip, and the forming can be performed such that spikes from the first strip connect with spikes of the second strip.

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.

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.

[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 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.

Provided are papermaking belts comprising a plurality of 3-D printed modules comprising first and second machine direction extending arms that may be interdigitated with one another and joined by a linkage pin. The 3-D printed modules generally have protuberances and apertures to facilitate molding and dewatering of the embryonic tissue web during manufacture. The protuberances are joined to, and extend from, the first web contacting surface of the module and are integrally formed therewith. In this manner the web contacting surface of the belt comprises a first and a second plane, where the second plane is generally defined by the upper surface plane of the protuberances. The apertures, which generally consist of both intra-module and inter-module apertures, allow water to be removed from a tissue web during manufacture.
