ABSTRACT:
The invention relates to a forming fabric, with a paper side fabric having paper side threads and with a wear side fabric having wear side threads. The paper side fabric and the wear side fabric are superimposed to one another and connected by binding threads weaving with both the paper side threads and the wear side threads, both extending in cross direction relative to the binding threads. The binding threads form part of the weave pattern of the paper side fabric and form part of the weave pattern of the wear side fabric, and alternate from weaving with the paper side fabric to weave with the wear side fabric and vice versa, thereby crossing each other forming crossing points. The wear side weave pattern is repeated by wear side repeat units, wherein the binding threads alternate such that one or less than one crossing point within each wear side weave repeat unit is formed and the ratio of the paper side threads to the wear side threads is greater than 1.
