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.

Binding structure of industrial fabric

An industrial two-layered fabric comprising an upper surface side fabric having an upper surface side warp and at least an upper surface side weft, and a lower surface side fabric comprising at least a lower surface side warp and at least a lower surface side weft bound by at least an upper surface side biding yarn and at least a lower surface side binding yarn, said industrial two-layered fabric is constituted by at least first pair of warps in which the upper surface side warp and the lower surface side warp are vertically arranged, at least second pair of warps in which the upper surface side binding yarn functioning as a binding yarn and the lower surface side binding yarn functioning as a binding yarn are vertically arranged, and at least third pair of warps where two upper surface side warps are adjacently arranged, said industrial two-layered fabric further comprises at least an auxiliary weft which isn't exposed to a surface of the fabric without being woven with any warp.

Industrial two-layered fabric

An industrial two-layer fabric of the contact-yarn binding type without independent binding yarns, at both ends. The upper surface side warp serving as the warp fabric yarn-contact binding yarn is not woven into the upper surface side weft at one or more points of a complete structure, and extends toward the lower surface side instead and is woven into the lower surface side weft at the lower surface side, and then, extends toward the upper surface sides to be woven into other upper surface side weft, while, the lower surface side warp is not woven into the lower surface side weft at a point where the upper surface side warp serving as the warp fabric yarn-contact binding yarn is woven into the lower surface side weft at the lower surface side, and extends toward the upper surface side instead to be woven into the upper surface side weft which is not woven into the upper surface side warp, at the upper surface side, and then extends toward the lower surface side to be woven into other lower surface side weft. The industrial two-layer fabric forms a joint loop by at least one end portion of the warp being turned back at both end portions in its longitudinal direction, and at least a longitudinal yarn in a complete structure includes at least one warp which forms a pair arranged to be opposite to the warp which is turned back for forming the joint loop, and, in a longitudinal structure, the number of knuckles of one of the warps forming the pair is the same as that of the other of the warps forming the pair and distances between said adjacent knuckles are substantially the same.
