Abstract
A paper machine wire for dewatering and sheet forming purposes is structured such that the tendency of causing wire marks is decreased and simultaneously a greater wearing capacity is gained by exchangeably working threads. The multi-layer paper machine wire includes an upper fabric layer and a lower fabric layer with each layer being connected to one another by binding thread. The lower fabric includes a weft thread that extends from a running side of the lower fabric to a center position and overlaps a warp thread. The weft thread protects the warp thread against wear and forms a cushion against wire marking.
