    Abstract: A two layer fabric has first, second, third and fourth upper side wefts contiguously and repeatedly arranged. Each of three contiguously arranged warps forms a knuckle over second, over third, and over second upper side wefts respectively to form a separation portion. At both sides of the separation portion, both the second and third upper side wefts form a float portion by passing over two or more warps. Adjacent to the float portion, one warp passes over the second and third upper side wefts successively and one or two warps adjacent thereto pass over the second or the third upper side weft to form an approach portion where the second and third upper side wefts approach. Crimp portions are formed to sandwich the separation portion where the first and fourth upper side wefts pass over warps which are common to those of the separation portion.

  • Patent number: 6660668
    Abstract: There is disclosed a woven webbing structure, which resists interwoven yarns from coming out from the surface of the webbing due to bending, or the like. This is achieved without any significant reduction in the strength or energy absorptivity of the webbing. The webbing includes warps that each have a cored yarn and a side yarn, and wefts interwoven therein. The cored yarn is set such that the elongation percentage thereof is smaller than, or the extensional rigidity thereof is larger than, that of the side yarn, and is twisted by single twisting or the like. As a result, unevenness is formed on the surface of the cored yarn and friction between the cored yarn and other yarns, that is, the side yarn or the weft increases. The frictional force between yarns functions for resisting free movement of the cored yarn due to bending of the webbing, thereby making it possible for the cored yarn to resist coming out from the surface of the webbing.

  • Patent number: 4998568
    Abstract: A papermaking wire of double layered fabric, consisting of a set of warp threads, yarns in machine direction, and a set of weft threads on the running side of the wire, yarns in cross machine direction, as well as a set of weft threads on the paper side of the wire, the last one consisting of at least two groups of weft threads differing from one another with respect to the outwardly located length of floatings. In order to avoid an unacceptable decrease of the stability of the wire and avoid markings in the paper as well as an essential reduction of drainage of the wire, if the number of cross threads on the paper side is increased, the wire is configurated such that it includes three groups of cross threads A, B, C on the paper side. Within one weave pattern each warp thread is transversing three weft threads succeeding one another on the paper side and running thereafter between the weft threads on the paper side and on the running side interlacing at least one weft thread on the running side.

  • Patent number: 4821780
    Abstract: A multi-layer fabric for paper-making comprising at least two fabric layers A and B, each of which is formed by inter-weaving respective warps and wefts. An upper-most layer A is woven as a plain weave 1/1 except at binding points S1, S3 and is adapted to support a paper-web thereon. A lower layer B is positioned below the upper-most layer A, and formed by warps 3 and wefts 4, 4a, each of which have larger diameters than those of the upper-most layer A. The upper-most layer A and the lower-most layer B are bound by means of a part 1a of the warps 1 of the upper-most layer A being interwoven with a part 4a of the wefts 4 of the lower-most layer, or by means of separate binder threads 5 other than the warps or wefts being interwoven with the upper-most layer A and the lower-most layer B. At the binding points, a warp 1a of the upper-most layer which intersects with a weft 4a of the lower-most layer B or with a binder thread 5 is extended under three successive wefts 2a.

  • Patent number: 4333502
    Abstract: An endless forming fabric for paper-making machine comprise at least two layers of transverse threads and one layer of longitudinal threads. The upper loops formed by the longitudinal threads cover from 3 to 7 transverse threads of the upper layer. The leading crossing points of these upper loops with the transverse threads are distributed in a weave pattern using at least five longitudinal threads. The weave pattern on the paper side of the fabric is selected so as to avoid alignment of the upper loops of adjacent threads and diagonal effects. The lower loops formed by the longitudinal threads, on the machine side of the fabric, pass each time only underneath a single transverse thread of the lower layer. The outer loops are so located that there is no gap in the longitudinal direction between each individual said outer loop of each said longitudinal thread and outer loops of the adjacent longitudinal threads.
