Infinity shape coil for spiral seams
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.
Seam for Endless Fabric Belt
An endless fabric belt having a seam region, the seam region comprising: a) machine direction (MD) threads; b) cross-direction (CD) threads interwoven with the MD threads; and c) termination zones distributed throughout the entire seam region, with each termination zone comprising two ends of an MD thread; wherein: a plurality of the CD threads are fusible, with the fusible (F) and non-fusible (N) CD threads distributed in a pattern throughout the seam region such that in a repeating unit of the pattern, the ratio of F threads to CD threads is at most 0.75; and a plurality of the termination zones further comprise at least one fusible CD thread attached to the MD thread in the termination zone.
Papermaking felt and method for manufacturing the same
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.
Woven base fabric with laser energy absorbent MD and CD yarns and tissue product made using the same
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.
FABRIC FOR A FIBER WEB PRODUCING MACHINE AND A METHOD FOR MAKING THE SAME
A fabric for a machine for producing a fiberweb, the fabric including a woven base structure including a first base element and a second base element, wherein the first base element includes a first flat woven base material and the second base element includes a second flat woven base material, wherein the first flat woven base material has a length of twice a length of the fabric and is folded in a middle, creating a first two-ply element and a first fold, wherein the second flat woven base material also has a length of twice the length of the fabric and is folded in a middle, creating a second two-ply element and a second fold, and wherein the first base element and the second base element is arranged so that at least one ply of the first two-ply element is positioned between plies of the second two-ply element.
Extruded paper machine clothing and method for the production thereof
A clothing for a machine producing and/or processing a fibrous web extending in longitudinal and widthwise directions, includes a basic structure providing dimensional stability in longitudinal and/or widthwise directions. The structure includes a band-shaped, one-piece grid having widthwise-adjacent first material strands and polymer material having lengths in a longitudinal direction, and adjacent second interconnected material strands and/or droplets and polymer material, contacting the first strands at contact points forming the grid. The strands and/or droplets are deposited by extrusion of the polymer materials in liquid or pasty state onto a depositing surface forming a portion or all of the grid in liquid or pasty state, the polymer materials are solidified, converting the portion or the grid from liquid or pasty to solidified, stable, self-supporting state producing bonding at the contact points, and removing the portion or the grid from the surface.
Basic structure of a clothing for a machine for producing or processing a fibrous material web and method for the production thereof
A basic structure of a clothing for a machine for producing or processing a fibrous web, in particular a paper, cardboard or tissue web. The basic structure has at least a first flat fabric of fabric type A and a second flat fabric of fabric type B, and, furthermore, two loop elements. The loop elements are formed in each case from a flat fabric piece which has a first portion of fabric type A and a second portion of fabric type B. The first portion is laid down on the second portion in such a way that the folding point is formed at a spacing of less than 5 cm, in particular less than 1 cm, from the changeover position between the fabric type A and the fabric type B. The first and the second flat fabric are arranged above one another, and the two loop elements are arranged in each case at a face-side, front end.
Binding structure of industrial fabric
A binding structure of an industrial fabric for binding both ends of a fabric with ends to form it into an endless type has loops formed by bending a portion or all ends of warp constituting the fabric at both ends and folding it back, the loop at the one end constitutes a binding loop which forms a common hole into which a core wire is introduced upon binding, the loop at the other end portion which is opposed to the binding loop to form a pair with the binding loop upon binding has a structure into which the binding loop is fitted and against which the binding loop is locked, and forms a loop hole into which the core wire is not introduced.
COVERING FOR A MACHINE FOR PRODUCING A FIBROUS WEB AND METHOD FOR PRODUCING A COVERING OF THIS TYPE
A covering is particularly suited for use in a machine for producing and/or finishing a paper, cardboard, tissue or pulp web. The covering has a basic structure formed as a part of a flat woven material, which flat woven material is designed as a woven material by interlacing warp threads and weft threads. The portion of the flat woven material has a plurality of sections that are formed integrally with each other, with at least one property of one of the sections differing from the respective property of at least one adjacent section.
REINFORCED ELEMENT FOR INDUSTRIAL TEXTILES
A reinforced element for use in the construction and assembly of an industrial textile, the element comprising a fibrous reinforcing material encapsulated by a thermoplastic polymer matrix, wherein: the thermoplastic polymer matrix comprises an amorphous polyester, a low-crystallinity polyester, polyphenylene sulphide (PPS), or a mixture thereof; the fibrous reinforcing material comprises continuous filaments selected from the group consisting of thermoplastic polymeric filaments, thermosetting polymeric filaments, glass fibers and a mixture thereof such that a majority of the continuous filaments are oriented in a first direction and the remainder of the continuous filaments are oriented in a second direction that is generally perpendicular to the first direction; a temperature at which the amorphous polymer substantially enters a liquid state, or the melting point of the low-crystallinity polyester, is at least 10 C. less than the melting point of the thermoplastic polymeric filaments; and the polymer matrix and the fibrous reinforcing material are both substantially transparent to radiant laser energy in a range of from about 800 nm to about 1200 run.
