    Abstract: An industrial fabric is described which comprises a woven fabric body having opposing ends. The fabric repeating weave pattern includes at least two systems of vertically stacked machine direction warp yarns interwoven with at least one system of cross machine direction weft yarns. On each end of the fabric at least some of the warp yarns form a first set of loops each of which is at a first angle to the machine direction, at least some of the warp yarns form a second set of loops each of which is at a second angle to the machine direction and each of the second set of loops is substantially concentric with the first set of angled loops to provide double end loops which can be seamed by using a coil seam or a pin seam. This fabric structure has the advantage that it is possible to use all of the fabric warp yarns in the loops, thus significantly increasing the tensile strength of the seam. It also permits the fabrication of a flatter seam.

    Abstract: A method of seaming an on-machine-seamable multiaxial papermaker's fabric to prevent yarn migration. The multiaxial fabric is in the form of an endless loop flattened into two layers along fold lines. CD yarns are removed from the folds to create extended ravel areas. This leaves the MD yarns unbound in the ravel areas. Seam loops are then formed from the unbound MD yarns at the folds. CD materials (e.g. continuous CD yarns) are affixed to (rewoven into) the fabric along the edges of the ravel area at each fold. The affixed CD materials bind the CD yarn tails along the edges of the ravel areas to prevent migration of CD yarn tails into the seam area.

  • Patent number: 7374639
    Abstract: A papermaking belt having a reinforcing structure and a pattern layer is disclosed. The reinforcing layer has a first layer of interwoven machine direction yarns and cross-machine direction yarns. The machine direction and cross-machine direction yarns of the first layer are interwoven in a weave. The pattern layer extends outwardly from and into the first layer. The pattern layer provides a web contacting surface facing outwardly from the first layer. The pattern layer further has at least one region having an amorphous pattern of elongate two-dimensional geometrical shapes having a longitudinal axis having an angle relative to either of the machine direction or the cross-machine direction. The amorphous pattern of two-dimensional geometrical shapes has a statically controlled degree of randomness.

  • Patent number: 7373957
    Abstract: A papermaking screen includes at least one individual fabric for the paper side and at least one individual fabric for the machine side. Each of those fabrics is provided with a set of weft yarns (4, 6) and warp yarns (1, 5). At least one part of the superimposed individual fabrics is interconnected via binder yarns (3). The two fabric layers (paper side and machine side) are connected by binder yarns that are fully integrated into the fabric structure of the paper side and are able to support the resulting binding point due to each binder yarn (3) engaging with warp yarns (1) of the individual fabric from above at defined points on the paper side, while at least one weft yarn (2) of the individual fabric engages with the warp yarns (1) from below on the opposite side so as to lean against it such that the binder yarns remain on one plane along with the weft and the remaining warp yarns.

  • Patent number: 7360560
    Abstract: A single layer papermakers fabric comprises machine direction (MD) warp yarns interwoven with cross-machine direction (CD) weft yarns to a repeating weave pattern requiring N sheds in the loom, N being an integer and at least 4. Each warp yarn follows a path in the paper side surface comprising four segments in each pattern repeat. In each of the first and third segments, the warp yarn interweaves with three consecutive weft yarns to form a double warp knuckle, and in the second and fourth segments, the warp yarn forms respectively a first and second MD float having unequal float lengths, at least one of the MD floats being over at least N consecutive weft yarns. The fabrics provide high air permeability, and increased surface contact area, stability and seam strength, and are particularly suitable for use as forming fabrics and through air dryer fabrics for tissue and towel products.

  • Patent number: 7357972
    Abstract: A liquid-permeable support for a paper machine clothing that is usable in the press section of a paper machine includes a support having at least two plies that brace against one another via discrete bracing elements. At the points where the plies brace against one another, there is applied on one or both sides an elastic coating which is embodied elastically in such a way that the spacing of the plies under pressure loading is decreased by elastic compression of the coating. Upon pressure relief the spacing is increased again by elastic recovery of the coating.

  • Patent number: 7357155
    Abstract: A multi-layer fabric which may be utilized in a papermaking process. The fabric layers are bound together by plural pairs of weft binder yarns. Each binder yarn within a pair weaves a different contour pattern and combines with the other binder yarn in that pair to form a plain weave pattern in the top layer. Each of the plural pairs is comprised of binding yarns that weave different contour patterns from the next pair.

  • Patent number: 7357157
    Abstract: In a repeating unit of a two-layer fabric, a first upper surface side warp forms a first upper surface side warp design. A second upper surface side warp forms a latent portion in which the second upper surface side warp passes between the two layers of the fabric. A first lower warp binding yarn and a second lower warp binding yarn form first and second knuckles respectively by passing over one or two upper surface side wefts at a position not adjacent to two knuckles of the second upper surface side warp in the latent portion. The first and second knuckles are formed at different positions. The first lower warp binding yarn, second upper surface side warp and second lower warp binding yarn cooperatively form a second upper surface side warp design similar to the first upper surface side warp design.

  • Patent number: 7306014
    Abstract: In a lower surface side layer of an industrial two-layer fabric, warps are formed by sequentially arranging a repeating design unit, in which one warp passes over six successive lower surface side wefts, passes under one lower surface side weft, passes over two lower surface side wefts, and passes under one lower surface side weft while shifting the design by three lower surface side wefts. Two adjacent lower surface side warps simultaneously weave therein, from the lower surface side, one lower surface side weft, whereby the lower surface side weft passes over two lower surface side warps and then passes under eight lower surface side warps to form a weft long crimp corresponding to eight lower surface side warps on the lower surface side surface.
