Abstract
Description
- This application claims the benefit of U.S. Provisional Application No. 61/414,944, filed Nov. 18, 2010.
- The disclosed invention is directed toward an improved construction for a reinforcing fabric for belts.
- Recent developments in high tension abuse resistant conveyor belt fabrics have created fabrics which are too thick and rigid to be used in multi-layer constructions. They either have too little crimp in the warp to allow multi-ply construction or are so thick the distance between two plies creates longitudinal flexibility and troughing issues. This invention takes the positives of the high tension fabrics and combines them with the benefits from using lighter weight conveyor belt fabrics.
- Most high tension/abuse resistant fabrics being produced today use a straight warp tension member. This straight warp yarn has 0-1% crimp which limits the ultimate elongation of the finished belt, but also makes it very rigid if produced in multi-ply constructions.
- High volume conveyor belt fabrics are produced using a plain, crowfoot, or twill pattern. These weave patterns can produce fabrics with 3-10% crimp. They excel in multi-ply conveyor belts but create too much stretch and poorer abuse resistance than their straight warp counterparts.
- This invention takes a crowfoot or twill pattern and improves its stretch and abuse characteristics by creating 2 layers. The two layers induce a moderate amount of crimp, 2-5%, which allow the fabric to be used in 2, 3, or 4 ply applications. They also improve the abuse resistance over standard weave patterns in that the warp yarns are protected by the weft yarns. The exposure of the warp yarns is kept to a minimum by the unique weave pattern.
- In accordance with the present invention, a reinforcing fabric for a belting is disclosed. The reinforcing fabric is a composite fabric which provides the belt with superior properties such as high rip resistance, transverse tear resistance, impact resistance, anti-fraying, and flexibility. In accordance with the present invention, the composite has two layers, the weft yarns have a corresponding binder, and there is a top warp yarn which covers some of the top weft yarns, and a bottom warp yarn which covers some of the bottom weft yarns.
-
FIG. 1 is a perspective view of a belting employing the inventive fabric in one of the plies; -
FIG. 2 is a schematic illustration of one embodiment of the inventive fabric; -
FIG. 3 is a pattern for a first embodiment of the inventive fabric; -
FIG. 4 is a schematic illustration of a second embodiment of the inventive fabric; -
FIG. 5 is a pattern for a second embodiment of the inventive fabric; - “Binder Yarn” denotes yarn that is used to bind together different yarns in a fabric.
“Fabric” denotes a network of essentially unidirectionally extending cords/yarns, which may be twisted, and which may in turn be composed of a plurality of a multiplicity of filaments (which may also be twisted).
“Crimp Percentage” is defined as the mean difference between the straightened yarn length and the distance between the ends of the yarn while in cloth, expressed as a percentage.
“Warp” refers to a network of essentially unidirectional extending cords/yarns, which extend in the longitudinal direction of the belt.
“Weft” (filling) refers to the cord/yarn placed at right angles to the warp cords/yarns.
“Woven Fabric” refers to the interlacing of two sets of yarn, the warp and weft yarns, at right angles.
“Plain Weave” refers to a type of weave wherein each warp yarn interlaces one yarn at a time with each weft yarn and vise versa. Plain weave fabric has the same appearance on both sides of the fabric.
“Twill Weave” refers to a type of weave wherein there are fewer interlacings between the warp and weft yarns than plain weave fabrics. Twill weaves are characterized by diagonal lines on the fabric. - Various aspects of the invention are presented in
FIGS. 1-5 which are not drawn to scale and in which like components are numbered alike.FIG. 1 illustrates a multi-ply belting 5 employing theinventive fabric 10. The length of thebelting 5 extends in the longitudinal direction L of the belt, while the width of thebelting 5 extends in the transverse direction T of the belt. The relative thickness of the layers is for illustrative purposes only. In each fabric ply, the warp yarns extend in the longitudinal direction L of the belt, while the weft yarns extend in the transverse direction T. - According to an aspect of the invention, a
composite fabric 10 for use in aconveyor belt 5 comprises afirst weft sheet 30, asecond weft sheet 40, atop warp yarn 1, abottom warp yarn 2, and a binder yarn B. - The
first weft sheet 30 is comprised of individual weft yarns W1-W3, wherein each yarn has anouter side 34 and an opposinginner side 36. - The
second weft sheet 40 is also comprised of individual weft yarns W4-W6, wherein each yarn has anouter side 44 and an opposinginner side 46. The second weft sheet yarninner side 46 is adjacent to the first weft sheet yarnsinner side 36. - According to an aspect of the invention, a
top warp yarn 1 extends at least in part between the first and thesecond weft sheet 30/40, and is at least in part woven around at least one first weft sheet yarnouter side 34. - According to an aspect of the invention a
bottom warp yarn 2 extends at least in part between the first and thesecond weft sheet 30/40, and is at least in part woven around at least one second weft sheet yarnouter side 44. - The
top warp yarn 1 does not weave around any secondweft sheet yarns 40, and thebottom warp yarn 2 does not weave around any firstweft sheet yarns 30. - The binder yarn B weaves alternately around a first weft sheet yarn
outer side 34 and a second weft sheet yarnouter side 44. - According to a further aspect of the invention, the
top warp yarn 1 extends around a single first weft sheet yarnouter side 34, and subsequently around two first weft sheet yarnsinner sides 36, and repeats this weave pattern. - According to another aspect of the invention, the
bottom warp yarn 2 extends around a single second weft sheet yarnouter side 44, and subsequently around two second weft sheet yarnsinner sides 46, and repeats this weave pattern. - In a further embodiment, the
top warp yarn 1 extends around a single first weft sheet yarnouter side 34, and subsequently around two first weft sheet yarnsinner sides 36, and repeats this weave pattern, and thebottom warp yarn 2 extends around a single second weft sheet yarnouter side 44, and subsequently around two second weft sheet yarnsinner sides 46, and repeats this weave pattern. - According to another aspect of the invention, a first weft sheet yarn having a top warp around its outer side (see W3) is adjacent to a second weft sheet yarn having a bottom warp around its outer side (see W4).
- In a preferred embodiment, the
top warp yarn 1 and thebottom warp yarn 2 weave through thefirst weft sheet 30 and thesecond weft sheet 40 respectively such that the resulting crimp is between 2%-5%. - This inventive composite fabric ply may be used in construction of a
conveyor belt 5. The inventive fabric may be employed as the sole reinforcing structure in a belt or combined with other layers for multiple ply beltings. Aconveyor belt 5 using this fabric may use just one ply of thiscomposite fabric 10, or multiple plies. If multiple plies of thiscomposite fabric 10 are used, they may be separated by plies ofrubber 20, or other elastomeric material. In a further embodiment of the invention, the top and bottom layers of a conveyor belt arerubber plies 20 andcomposite fabric plies 10 are alternated throughout the construction. The number of plies and the combinations employed are dependent upon the desired application for the belting. - In another embodiment of the invention, the binder yarn B weaves at least around a first weft sheet yarn
outer side 34, and a second weft sheet yarnouter side 44. - In a further aspect of this embodiment, the
top warp yarn 1 extends around a single first weft sheet yarnouter side 34, and subsequently around three first weft sheet yarnsinner sides 36, and repeats this weave pattern. - In a further aspect of this embodiment the
bottom warp yarn 2 extends around a single second weft sheet yarnouter side 44, and subsequently around three second weft sheet yarnsinner sides 46, and repeats this weave pattern. - According to another aspect of this embodiment, the first weft sheet yarn W1 having the
top warp 1 around the first weft sheet yarnouter side 34 is adjacent to the second weft sheet yarn W5 having thebottom warp 2 around the second weft sheet yarnouter side 44. - In a further embodiment of this invention, the binder yarn B weaves around two adjacent first weft sheet yarn
outer sides 34, and then a second weft sheet yarnouter side 44, and repeats this pattern.
