Abstract
Forming fabric that includes a top layer having a plurality of first top warp yarns woven with a plurality of top weft yarns. A bottom layer includes a plurality of first bottom warp yarns woven with a plurality of bottom weft yarns. A plurality of second top warp yarns is woven with some of the plurality of top weft yarns and with some of the plurality of bottom weft yarns. A plurality of second bottom warp yarns is woven with some of the plurality of top weft yarns and with some of the plurality of bottom weft yarns. At least one of the plurality of second top warp yarns weaves to the bottom layer with a short plain weave. At least one of the plurality of second bottom warp yarns weaves to the bottom layer with a short plain weave.
