At least one infrared element arrangement having at least one infrared element (3) comprising a plurality of infrared radiators (4) is mounted on a frame moveable with respect to a synthetic filter fabric mounted to a filtering surface. The frame may have wheels or the like such that the infrared radiators may be moved along the length of the filtering surface to heat the synthetic filter fabric (6) to a temperature of 100 to 160° C. for shrinking the fabric (6) on the filtering surface (5).

A clothing for paper or pulp dewatering machines comprising monofilaments comprising a partially aromatic polyamide. A machine-side fabric layer is provided, and at least the machine-side fabric layer comprises monofilaments with a partially aromatic polyamide. The clothing comprises or is formed by longitudinal threads extending in a running direction and transverse threads extending transversely to the longitudinal threads, and at least some of the transverse filaments are monofilaments with a partially aromatic polyamide.

A method of forming a fibrous web including the steps of providing a fiber slurry, depositing the fiber slurry between an inner forming wire and an outer forming wire, wherein the outer forming wire comprises a structured fabric and the inner forming wire contacts a segment of a forming roll, and rotating the forming roll so that the fiber slurry moves into contact with the structured fabric.

A fibrous material accumulating apparatus includes a dispersing section which disperses a material containing fibers, a belt which accumulates the dispersed material, and a suction section provided on a side of the belt opposite to the dispersing section, in which the dispersing section includes a storage section including a screen, a supply section which supplies the material to the storage section, and a rotating body which is provided inside the storage section and agitates the material supplied into the storage section, and the storage section includes a communicating port which causes an inside and an outside of the storage section to communicate with each other and is provided at a different position from the screen.

A papermaking belt including zones of material laid down successively using a 3D printing process. The zones include at least a pocket zone configured to form three dimensional structures in a paper web by applying vacuum to pull the paper web against the pocket zone. In at least one exemplary embodiment, the zone also include at least one vacuum breaking zone configured to limit an amount of paper fibers pulled through the pocket zone by the applied vacuum.

A method for producing an edge protector on a clothing for a machine producing or finishing a fibrous, paper, cardboard or tissue web, includes providing a clothing formed substantially from a woven fabric with crossing weft and warp threads and opposite side edges, applying a film strip onto a surface of one side edge and, immediately before bringing the film strip into contact with the clothing, surfaces of the film strip and the clothing facing each other are heated to slightly melt the surfaces. A pressing force exerted on the film strip applied to the surface of one of the side edges, results in the film strip penetrating at least partially into the woven fabric. That side edge of the clothing with the film strip is cooled, resulting in a stable, particularly integrally joined and form-locking connection between the film strip and the side edge of the clothing.

A papermaking belt including zones of material laid down successively using a 3D printing process. The zones include at least a pocket zone configured to form three dimensional structures in a paper web by applying vacuum to pull the paper web against the pocket zone. In at least one exemplary embodiment, the zone also include at least one vacuum breaking zone configured to limit an amount of paper fibers pulled through the pocket zone by the applied vacuum.

A woven fabric is used in a machine to produce a fiber web. The woven fabric has a machine direction, a cross machine direction, a paper side and a machine side. The paper side is formed by interwoven warp yarns and weft yarns. The paper side contains a plurality of twill lines, each twill line being formed by a plurality of neighboring flotations of warp yarns. The twill lines contain an MD vector component directed in the machine direction and a CD vector component directed in the cross machine direction. At least some twill lines are diagonal twill lines meaning that the CD vector component is unequal to zero. The plurality of diagonal twill lines contains first diagonal twill lines and second diagonal twill lines, the CD vector components of the first diagonal twill lines have an opposite sign to the CD vector components of the second diagonal twill lines.

Disclosed are woven papermaking fabrics having a textured sheet contacting surface with machine and cross-machine direction topography. The machine direction (MD) topography may be imparted by substantially MD oriented protuberances comprising a warp strand supported by a shute strand. The cross-machine direction (CD) topography may be imparted by substantially CD oriented protuberances comprising a shute strand supported by a warp strand. The CD protuberances may extend continuously in the CD and intersect the MD oriented protuberances to form discrete pockets there between. The pockets may have a variety of shapes and size depending on the MD and CD oriented protuberance. In certain instances the pockets may be rectilinear and have a pocket depth greater than 1.0 mm and a pocket angle greater than 28 degrees.

Provided are woven papermaking fabrics having a web contacting surface having protuberances formed from woven warp and shute filaments. The protuberances, which may be oriented in the machine direction (MD) converge, merge or diverge and may be arranged to form a pattern. In certain instances the protuberance may comprise a first MD oriented protuberance having an element angle from about 0.5 to about 15 degrees, a second MD oriented protuberance having an element angle from about −0.5 to about −15 degrees wherein the first and second protuberances converge at a convergence area to form a third MD oriented protuberance having an element angle from about −15 to about 15 degrees.
