Abstract
A papermaking fabric includes a system of warp yarns interwoven with a system of weft yarns. The system of weft yarns includes groups of weft yarns, each of the groups being formed by a plurality of adjacent weft yarns weaving in the group side-by-side the same weave path with the warp yarns. A method of manufacturing such a papermaking fabric is also provided.
Claims18
A papermaking fabric, comprising:
- a system of warp yarns interwoven with a system of weft yarns, wherein the system of weft yarns further comprises a plurality of groups of weft yarns and a plurality of ungrouped weft yarns, each of said groups formed by a plurality of adjacent weft yarns weaving in said group side-by-side the same weave path with said warp yarns, the papermaking fabric being a dryer fabric, said plurality of ungrouped weft yarns including, between each of said groups of weft yarns, a plurality of adjacent weft yarns which weave different weave paths relative to one another with said warp yarns.
The papermaking fabric according to clam 1, wherein the adjacent weft yarns in each group have different compositions.
A papermaking machine comprising a dryer section, wherein the dryer section is a single tier dryer section comprising a dryer fabric, said dryer fabric comprising a system of warp yarns interwoven with a system of weft yarns, wherein the system of weft yarns further comprises a plurality of groups of weft yarns and a plurality of ungrouped weft yarns, each of said groups formed by a plurality of adjacent weft yarns weaving in said group side-by-side the same weave path with said warp yarns, said plurality of ungrouped weft yarns including, between each of said groups of weft yarns, a plurality of adjacent weft yarns which weave different weave paths relative to one another with said warp yarns.
A method of manufacturing a papermaking fabric with a woven structure by weaving of weft yarns with warp yarns comprising the steps of:
- inserting a plurality of ungrouped weft yarns, said plurality of ungrouped weft yarns including a plurality of adjacent weft yarns which weave different weave paths relative to one another with said warp yarns;
- inserting a first plurality of weft yarns at the same time by one weft yarn shoot such that said first plurality of weft yarns weave side-by-side the same weave path with said warp yarns and thereby form a first group of weft yarns;
- and
- inserting a second plurality of weft yarns at the same time by one weft yarn shoot such that said second plurality of weft yarns weave side-by-side the same weave path with said warp yarns and thereby form a second group of weft yarns, said plurality of ungrouped weft yarns being between said first and second groups of weft yarns, the papermaking fabric being a dryer fabric.
