Claim:
A compound paper making fabric comprising: a paper side fabric having paper side threads, a wear side fabric having wear side threads and superimposed onto the paper side fabric, the wear side fabric and the paper side fabric connected by a first binding thread and a second binding thread, wherein the first binding thread and the second binding thread are woven with the paper side threads and with the wear side threads both extending in a cross direction relative to the first and second binding threads, the first and second binding threads forming a part of a first weave pattern of the paper side fabric and forming part of a second weave pattern of the wear side fabric, wherein the first and second binding threads alternate from weaving with the paper side fabric and the wear side fabric, thereby forming a plurality of crossing points, wherein the second weave pattern has a predetermined wear side weave repeat unit, 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 one of 3:2 and 5:3, wherein the first and second binding threads alternate such that each of the first and second binding threads complete ≧1 repeats of a wear side weave repeat unit before exchanging onto the paper side, wherein the paper side fabric has a plain weave formed by the paper side threads and the first and second binding threads.
