Paper machine clothing and method of producing the same
A paper machine clothing has a plurality of through-channels formed in a usable region. The through-channels extend through the substrate to connect the upper and lower sides. The through-channels are non-cylindrical with a cross-sectional area becoming smaller along a thickness direction of the substrate from the upper side to a middle region of the substrate. An upper rim of at least one of the plurality of through-channels directly contacts an upper rim of at least one other neighboring through-channel of the plurality of through-channels, wherein the upper rims of both neighboring through-channels have at least three common local maxima, including two outer common local maxima and one intermediate common local maximum that is located between the two outer common local maxima. There is also described a method of producing such a paper machine clothing.
COMPOSITE LAMINATED PAPERMAKING FABRICS AND METHODS OF MAKING THE SAME
A structured tissue belt assembly including a supporting layer and a nonwoven web contacting layer. The supporting layer has a top surface and a bottom surface and is formed of monofilaments including one or more layers of warp yarns interwoven with weft yarns in a repeating pattern. At least one of: a) at least some of the warp yarns; or b) at least some of the weft yarns, include laser energy absorbent material, and at least one of: a) at least some of the warp yarns; or b) at least some of the weft yarns include laser energy scattering material. Laser welds attach the bottom surface of the web contacting layer to the top surface of the supporting layer at points where the web contacting layer contacts the at least one of: a) the at least some of the warp yarns; or b) the at least some of the weft yarns that include laser energy absorbent material.
Deflecting member for making fibrous structures
A deflection member that includes a reinforcing member and a plurality of tiles fastened to the reinforcing member.
Paper machine clothing and method of producing the same
A paper machine clothing has a substrate with an upper side, a lower side, two lateral edges and a usable region between the two lateral edges. The usable region is formed with a plurality of through-channels extending through the substrate and connecting the upper side with the lower side. The through-channels are non-cylindrical with a cross sectional area becoming smaller when going in a thickness direction of the substrate from the upper side to a middle region of the substrate between the upper side and the lower side, wherein a shape of the cross sectional area of at least one through-channel, preferably of all through-channels, of the plurality of through-channels changes proceeding in the thickness direction of the substrate from the upper side to the lower side.
High Permeability Texturing Belt
The instant invention relates to an industrial fabric for producing a textured product, wherein the industrial fabric has a first layer, such as a woven base fabric, and a second layer, such as a film, that extends over at least a portion of a top surface of the first layer. The second layer has macro voids and micro voids. In certain embodiments, the macro voids impart a texture in a fiber product produced on the industrial fabric, whereas the micro voids limit or prevent penetration of the fibers of the product into the micro voids while at the same time increasing permeability of the industrial fabric.
Clothing for a machine for producing a fibrous material web
Clothing is provided for a machine for producing a fibrous web, in particular a paper, board or tissue web. The clothing has a substrate. The substrate has a top side, an underside, two side edges and a useful region between the two side edges. The useful region has a plurality of through-channels, which connect the top side to the underside of the substrate. An inner surface of at least one through-channel, preferably of the majority of all the through-channels, more preferably of all the through-channels in the useful region of the substrate, has a mean roughness depth that is greater than 4 μm, preferably greater than 6 μm, more preferably greater than 8 μm. The clothing of this type is produced using a laser.
PAPER MACHINE CLOTHING AND METHOD OF PRODUCING THE SAME
A paper machine clothing has a plurality of through-channels formed in a usable region. The through-channels extend through the substrate to connect the upper and lower sides. The through-channels are non-cylindrical with a cross-sectional area becoming smaller along a thickness direction of the substrate from the upper side to a middle region of the substrate. An upper rim of at least one of the plurality of through-channels directly contacts an upper rim of at least one other neighboring through-channel of the plurality of through-channels, wherein the upper rims of both neighboring through-channels have at least three common local maxima, including two outer common local maxima and one intermediate common local maximum that is located between the two outer common local maxima. There is also described a method of producing such a paper machine clothing.
Manufacturing process for papermaking belts using 3D printing technology
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.
Deflecting Member for Making Fibrous Structures
A deflection member that includes a reinforcing member and a plurality of tiles fastened to the reinforcing member.
Paper machine clothing and method of producing the paper machine clothing
A substrate of a paper machine clothing has a usable region formed with through-channels that are non-cylindrical with a cross-sectional area becoming smaller from an upper side to a middle region of the substrate. An upper rim of at least one of the through-channels directly contacts an upper rim of at least one neighboring through-channel and the upper rims have common local maximum. A sectional plane parallel to the thickness direction of the substrate defines an intersecting line with a sidewall of a neighboring through-channel. The intersecting line has a convexly shaped first portion, a concavely shaped second portion, and a third portion that is again convexly shaped going from the at least one common local maximum toward the middle region of the substrate. There is also described a method of producing such a paper machine clothing.
