Abstract
A forming fabric having a set of paper side warp yarns, which interlace with both a set of paper side weft yarns and a set of binder wefts and a set of machine side warp yarns which interlace with a set of machine side weft yarns and the set of binder weft yarns, whereby the binder weft yarns are disposed in groups of at least two, and whereby both binder weft yarns of at least one binder group, in total, form fewer knuckles over the paper side warp yarns than the paper side weft yarns.
