  • the present invention relates to improved methods for weaving colored or patterned floor coverings.
  • the yarns that form the color or pattern of the floor covering are woven in the weft direction.
  • Such a method is opposite the traditional method of machine weaving, in which the yarns that make up the color or pattern are woven from the warp direction.
  • the advantages of weaving a floor covering with the color or pattern yarns on the weft is that the colors and/or pattern may be changed much more easily than in methods where the yarns that make up the pattern run in the warp direction.
  • the fact that the colors may be changed easily and inexpensively as compared to conventional methods may allow a manufacturer to make available a wider range of floor coverings than has been feasible in the past.
  • the other advantages of such embodiments is that, by facilitating quick and efficient production of large and small batches of floor coverings with different colors or patterns, they may also reduce the need to stock large quantities of floor coverings and may therefore result in substantial savings in the form of reduced inventory costs.
  • the present invention also relates to methods for joining segments of colored or patterned floor coverings.
  • One embodiment of the invention provides a method for weaving a colored or patterned floor covering.
  • This method 50 illustrated in steps 52 - 56 of FIG. 1, comprises weaving a first set of yarns in a warp direction with a second set of yarns in a substantially perpendicular weft direction, such that the weft yarns form at least a substantial portion of the color or pattern of the floor covering.
  • this embodiment allows the colors or pattern to be changed by simply changing one or more of the relatively small number of yarns that make up the weft. The warp yarns do not need to be reconfigured.
  • the weft yarns may form more of the visible part of the floor covering than is formed by the warp yarns, may form substantially more of the visible part of the floor covering than is formed by the warp yarns, or may form substantially all of the visible part of the floor covering.
  • “Visible part” means that portion of the floor covering that can be seen when the floor covering is placed on a floor or other flat surface, uncovered by furniture or any other objects, as if for normal use. Ordinarily, the visible part will be the floor covering's top face, exclusive of portions covered by edging or the like.
  • the weft yarns may make up at least about 15%, 25%, 50%, 75%, or 95% of the visible part the floor covering, such percentages to be measured by selecting a fixed area of the visible part and determining, by visual, optical, mechanical, digital, or other means, the percentage of the fixed area that is occupied by weft yarns. It has been found that increasing the proportion of the visible part that is comprised of weft yarns allows the appearance of the floor covering to be changed more easily.
  • the set of weft yarns may be one or more colors and, as described above, may comprise varying portions of the color or pattern of the floor covering.
  • the weft yarns may include yarns that form the color or pattern of the floor covering, as well as yarns that have a principal purpose of tying other yarns or portions of the floor covering together.
  • the set of warp yarns may comprise binder yarns, which may operate to tie the various yarns and layers together, and stuffer yarns, which may provide thickness, durability, and weight.
  • the binder yarns at least a portion of which may be visible in the finished product, may in some embodiments be of a color that is neutral in value, such as an off-white or a light brown. In other embodiments, the binder yarns may not be neural in value.
  • the color of the binder yarns may contribute to the overall appearance of the floor covering, their contribution is generally less than that of the weft yarns.
  • the color of the stuffer yarns may be less important because they are generally not visible in the finished product.
  • composition of the warp and weft yarns is not critical to the invention, and any of the below described embodiments may be constructed of any suitable type of yarn, including, for example, natural fibers such as woolens and cottons, synthetic materials such as rayon, nylon, acrylic, and polyester, and/or any other suitable material or combination of materials.
  • the yarns may have any suitable or desired colors, textures, or other aesthetic characteristics or combination of characteristics.
  • Floor coverings according to the invention may be woven on industrial fabric looms, such as those manufactured by Lindauer Domier GmbH of Lindau, Germany.
  • the invention is not limited to any particular brand, type, or model of loom, however, and any suitable loom may be used, as would be appreciated by one of skill in the art.
  • the colored yarns are generally thicker than the other yarns, in part because they are intended to provide the material with its appearance.
  • the colored yarns would be expected to cause problems if machine woven in the weft direction in a conventional manner because their thickness would create a large amount of tension on the warp and/or weft yarns as a result of the beat up. In some cases, the amount of tension could be sufficient to prevent the warp yarns from being fully hidden and/or could cause failure of one or more warp yarns.
  • the floor covering is woven such that relatively thin binder and stuffer warp yarns are woven with weft yarns that are thicker than a traditional weft material.
  • the binder yarns that are visible on the face of the material are generally uniform in color.
  • the result is a floor covering that has the appearance of being composed of a grid of small squares or rectangles, not unlike a traditional “needlepoint” material.
  • the stuffer yarns may be of varying thickness and densities, so as to provide the appropriate thickness, durability, and/or weight to the floor covering.
  • FIG. 2 shows a portion of a cross-section of an illustrative “needlepoint”-type floor covering according to the invention.
  • the cross-section of FIG. 2 is taken in the weft direction and shows the weft yarns in profile and the warp yarns in cross-section.
  • FIG. 2 depicts the main body 102 of the floor covering, including top face 104 and bottom face 106 , as well as the seam selvedge area 108 .
  • the floor covering of FIG. 2 employs three types of warp yarns, primary binders 170 a - c , secondary binders 180 a - c , and stuffers 190 , and six weft, or “pick,” yarns.
  • picks 110 and 140 lie principally on the top face 104 of the floor covering
  • picks 120 and 150 lie principally on the bottom face 106 of the floor covering.
  • the remaining picks 130 and 160 are binder wefts that operate, as shown, to tie the warp yarns together.
  • the weft yarns may be each be a different color, allowing the floor covering of this embodiment to have as many as six different colors on the weft.
  • the warp yarns, while commonly neutral, may also be colored. As noted, by providing the color on the weft, as opposed to on the warp, some or all of the colors of the pattern may easily be changed, as may the pattern itself.
  • FIG. 3 is a perspective view of a portion of the top face of the floor covering of FIG. 2 in which the spacing between the yarns has been enlarged for purposes of clarity. From this view, it can be seen that primary binders 170 a - c lie largely on the top face of the floor covering and, in combination with secondary binders 180 a - c , impart a needlepoint-like appearance to the material. It should be noted that, in this and the other illustrated embodiments, primary and secondary binders 170 , 180 may be fed from a different beam than the stuffers 190 .
  • FIG. 3 also illustrates variable interlacement, such as may be used to impart a particular pattern or design to the floor covering.
  • a first warpwise portion defined by picks 10 a - 160 a has picks 10 a and 140 a that lie entirely on the face of the floor covering except where they pass under primary binders 170 a - c , and picks 120 a and 150 a that lie entirely under the face of the floor covering, except where they pass over secondary binders 180 a - b .
  • picks 110 b and 140 b lie entirely under the face of the floor covering, except where they pass over secondary binders 180 a or 180 b
  • picks 120 b and 150 b lie on the face of the floor covering, except where they pass under primary binders 170 a - c .
  • This variable interlacement pattern is merely illustrative, however, and it should be understood that the invention contemplates any number of other patterns, variable or constant, as would be appreciated by one of skill in the art.
  • FIG. 4 illustrates a portion of another “needlepoint” embodiment that uses eight weft yarns in conjunction with primary binders 270 a - c , secondary binders 280 a - c , and stuffers 290 .
  • the floor covering of this embodiment may thus have as many as eight colors on the weft.
  • picks 210 and 240 lie principally on the top face 104 of the floor covering, and picks 220 and 250 , as well as picks 264 and 268 , lie principally on the bottom face 106 of the floor covering.
  • the remaining picks 230 and 260 are binder wefts that operate to tie the neutral warp yarns together.
  • FIG. 5 is a perspective view of a portion of the face of the floor covering of FIG. 4 in which the spacing between the yarns has been enlarged for clarity. From this view it can be seen that, similar to the floor covering of FIG. 2, primary binders 270 a - c lie largely on the face of the fabric and, in combination with secondary binders 280 a - c , impart a needlepoint-like appearance to the floor covering.
  • FIG. 5 also illustrates a variable interlacement pattern.
  • picks 210 a and 240 a lie entirely on the face of the floor covering except where they pass under primary binders 270 a - c
  • picks 220 a , 264 a , 250 a , and 268 a lie entirely under the face of the floor covering, except where they pass over secondary binders 280 a - c .
  • picks 210 b and 240 b lie entirely under the face of the floor covering, except where they pass over secondary binders 280 a - b
  • picks 220 b and 250 b lie on the face of the floor covering, except where they pass under primary binders 270 a - c .
  • This variable interlacement pattern is also only illustrative, however, as the invention includes any number of other variable or non-variable patterns.
  • the floor covering of FIG. 6 is a third exemplar “needlepoint” construction that employs ten weft yarns in conjunction with primary binders 370 a - c , secondary binders 380 a - c , and stuffers 390 .
  • the floor covering of this embodiment may thus have as many as ten colors on the weft.
  • picks 310 and 340 lie principally on the top face 104 of the floor covering, and picks 320 , 364 , 366 , 350 , 368 , and 367 lie-principally on the bottom face 106 of the floor covering.
  • the remaining picks 330 and 360 are binder wefts that operate to tie the neutral warp yarns together.
  • FIG. 7 is a perspective view of a portion of the face of the floor covering of FIG. 6 in which the spacing between the yarns has been enlarged for clarity. From this view it can be seen that, similar to the floor covering of FIGS. 2 and 4, primary binders 370 a - c lie largely on the face of the fabric and, in combination with secondary binders 380 a - c , impart a needlepoint-like appearance to the floor covering.
  • picks 310 a and 340 a lie entirely on the face of the floor covering except where they pass under primary binders 370 a - c
  • the remaining picks lie entirely under the face of the floor covering, except where they pass over primary binders 370 a - c , in the case of picks 330 and 360 , or over secondary binders 380 a - c , in the case of the remaining picks.
  • pick 310 a lies principally on the face of the floor covering between primary binders 370 a and 370 c
  • pick 340 b lies principally on the face between primary binders 370 a and 370 b , but both are largely buried otherwise.
  • the weft yarns of the “needlepoint” embodiment may be one or more colors and may have any desired uniform or non-uniform size, weight, texture or appearance. In one embodiment, for example, weft yarns of varying thicknesses may be used to achieve different aesthetic effects.
  • Some embodiments of the “needlepoint” construction may use weft yarns with a Philadelphia or Bradford count in the range of 3/18 to 1/110 (worsted 3/1.54 to 1/3.1; approximately 288 to 1,760 yards per pound), or 4/32 to 2/65 (worsted 4/3.6 to 2/3.71; approximately 512 to 1,040 yards per pound), or 3/36 to 2/55 (worsted 3/3.09 to 2/3.14; approximately 576 to 832 yards per pound).

The use of such a process may speed up production of floor coverings and/or may facilitate the production of a large number of orders for floor coverings of the same pattern but different sizes.
  • a border may be positioned along all or a portion of one or more edges of the floor covering to further strengthen the edges and reduce the possibility of fraying.
  • a border which may be adhered to the floor covering by stitching, adhesive, or any other suitable means, may cover the ends of some or all of the warp and/or weft yarns to prevent fraying and may comprise any suitable material or materials, including cloth, paper, plastic, or leather, among others. If the floor covering is circular, the border can be applied along the circumference.
  • Another aspect of the present invention provides a method for joining segments of a woven floor covering. Such segments would be employed, for example, where it is desired to produce a floor covering wider than the operative width of the loom, such as in the case of a wall-to-wall carpeting.
  • At least two segments of floor covering material are provided, each comprising a first set of yarns that are woven in a warp direction, and a second set of yarns that are woven in a weft direction.
  • Each segment of floor covering will have a selvedge edge running along at least one warpwise side as a by-product of the weaving process.
  • the two segments are aligned such that their warp yarns are parallel and the respective selvedge edges of the sides to be joined are adjacent to each other.
  • the adjacent selvedge edges are sliced along their outside edges, resulting in an upper selvedge portion 109 a and lower selvedge portion 109 b , such as can be seen in, for example, FIG. 2.
  • the respective lower selvedge portions 109 b are then either folded back under the main bodies 104 of the floor covering segments or simply cut away, and the upper selvedge portions 109 a are then stitched together in a conventional manner to join the two segments.
  • the inventive floor coverings may be used in situations that call for floor coverings that are larger than the operative width of the loom, and the advantages associated with the inventive method of weaving with the color on the weft, as discussed above, can be extended to a wider variety of applications, such as wall-to-wall carpeting.
  • the combination of weaving with the color on the weft and the above-described joinery method may therefore allow a wide variety of large colored and patterned floor coverings, such as wall-to-wall carpets, to be produced and sold without the expense associated with changing thousands of creels and without the expense of maintaining a large inventory.
