Abstract: 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.

Abstract: 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.

Abstract: A seaming element for seaming industrial textiles for filtration or other uses, an industrial textile with seaming elements, and a method of seaming such textiles. The seaming element is secured to a first seamable end or edge of the fabric, and includes at least one extension member, which can be a channelled protrusion, and which is engageable with a corresponding at least one extension member of a corresponding seaming element secured to the second seamable end or edge. The seaming elements are configured and dimensioned so that when the extensions or protrusions of the two seaming elements are aligned together and engaged, in some embodiments being secured by a pintle, they have a thickness which is compatible with the caliper of the finished fabric, to form a secure seam while avoiding or minimizing any discontinuity or irregularity in the finished fabric.

Abstract: A nonwoven industrial fabric, and a method of constructing the fabric. The fabric comprises at least one layer of a polymeric film having a plurality of apertures extending from an upper surface through to a lower surface. Adjacent pairs of the apertures define land areas therebetween, and selected land areas comprise protrusions extending from at least one of the upper surface and the lower surface of the layer to form a profile to the respective surface. The method comprises optionally pre-embossing the film, cutting the film to provide the plurality of apertures, applying pressure to selected land areas to form the protrusions to create a contoured profile, and treating the film to set the contoured profile. Additional surface treatment can be provided, and two or more layers can be secured over each other for multilayer fabrics. The invention provides a simplified and economical construction, while maintaining stability and strength.

Abstract: A seaming element for joining opposed ends of woven or nonwoven industrial textiles, textiles including seaming elements, and methods of making a seam area for textiles. The seaming element comprises a continuous filamentary structure, configured as first and second layers of aligned looped segments, each segment of one layer being connected to adjacent segments of the other layer by a connecting portion. The seaming elements can be bonded directly to the fabric edges, or inserted into the fabric so that free ends of the looped segments engage and are secured by selected MD yarns or components. Connecting portions of complementary elements when interdigitated together define a continuous channel to receive a pintle. The seaming element is readily and securely installed in the textiles, and overcomes problems of alignment of fabric ends for securing a seam, while minimizing any disruption in fabric properties adjacent the seam area.

Abstract: A seaming element and a method of seaming an industrial textile. The seaming element comprises first and second components, each constructed of a substantially planar polymeric film, comprising a textile body contacting portion and a free edge, and at least one row of pairs of substantially parallel slits spaced across the component, the slits having first ends substantially equidistant from the free edge of the component, and the pairs of slits defining strips which are deformable out of a plane of the film. When the two components are attached respectively to textile edges to be seamed, and the components are brought together, deformed strips of the first component are alignable with deformed strips of the second component to interengage the two components and to define a channel for a seam securing means, thus providing a simple and secure seam which is compatible with the properties of the textile body.
