Abstract
A multi-layer paper machine wire includes an upper fabric layer, a lower fabric layer and an additional layer disposed between the upper and lower fabric layers. The additional layer includes weft threads that alternate with binding threads. Warp threads of the upper fabric layer run over the weft threads of the additional layer and are interwoven with binding threads of the additional layer. Likewise, weft threads of the lower fabric layer run below the weft threads of the additional layer and are interwoven with binding threads of the additional layer.
