Joining loop structure of industrial multilayer fabric

摘要

A multilayer fabric is joined by engaging joining loops formed at both ends of a disjoined industrial multilayer fabric having wefts and warps in layers. The joining loops are formed by folding back some or all the end portions of warps. The both ends of the fabric are joined by engaging the loops to form a common hole and inserting a core wire into the common hole. At least one upper side weft remains while a lower side weft below the remaining upper side weft is removed at the both ends of the fabric. The common hole and the core wire inserted therein are located below the remaining upper side weft. The folded portions of the warps are interwoven with wefts of a normal portion of the fabric.

1. A joining loop structure of an industrial multilayer fabric comprising:
wefts and warps arranged in layers; the industrial multilayer fabric comprising, at both end portions, joining loops of some or all the end portions of warps being folded back to form at least one common hole by engaging the joining loops at the both end portions of the fabric, a core wire is inserted into the common hole; wherein the joining loop structure is formed by leaving at least one remaining upper side weft at the both end portions and removing a lower side weft located below the remaining upper side weft; folded back end portions of the warps are interwoven with the wefts of normal portions of the industrial multilayer fabric; the common hole and the core wire inserted into the common hole are located below the at least one remaining upper side weft; upper side warps do not interweave lower side wefts and lower side warps do not interweave upper side wefts; the folded back end portions of the upper side warps are interwoven with the upper side wefts of the normal portions; and the folded back end portions of the lower side warps are interwoven with the lower side wefts of the normal portions.
