Method for preparing a seam area for a PMC base fabric

摘要

A process for preparing a seam area for a paper machine clothing (PMC) base fabric includes the steps of: forming the PMC base fabric by flat-weaving, the PMC base fabric including warp yarns extending in machine direction and weft yarns extending in cross machine direction and interwoven with the warp yarns, the weft yarns including first weft yarns and a second weft yarn, the second weft yarn being a multifilament yarn, the warp yarns, the first weft yarns, and the multifilament yarn being woven together on a loom in an original weaving process, the multifilament yarn being positioned in an anticipated seam area; and folding over the PMC base fabric, after weaving the multifilament yarn with the warp yarns, to form a seam loop of the PMC base fabric such that the multifilament yarn is a first one of the weft yarns on a sheet side of the seam loop.

1. A process for preparing a seam area for a paper machine clothing (PMC) base fabric, said process comprising the steps of:
forming the PMC base fabric by flat-weaving, the PMC base fabric including a plurality of warp yarns extending in a machine direction and a plurality of weft yarns extending in a cross machine direction and interwoven with said plurality of warp yarns, said plurality of weft yarns including a plurality of first weft yarns and at least one second weft yarn, said at least one second weft yarn being a multifilament yarn that is different from said plurality of first weft yarns, said plurality of warp yarns, said plurality of first weft yarns, and said at least one multifilament yarn being woven together on a loom in an original weaving process, said at least one multifilament yarn being positioned in an anticipated said seam area; and folding over the PMC base fabric, after weaving said at least one multifilament yarn with said plurality of warp yarns, to form a seam loop of the PMC base fabric such that said at least one multifilament yarn is a first one of said plurality of weft yarns on a sheet side of said seam loop.
