A paper machine fabric, comprising: at least two separate layers formed using at least two separate yarn systems: a yarn system constituting the paper side and comprising warps and wefts; and a yarn system constituting the machine side and comprising warps and wefts, the yarn systems being arranged to form independent structures in the warps and wefts of the fabric and the structures being bound together by means of binder yarns; a binder yarn being arranged to form part of a weave of a layer on the paper side surface and arranged to be interwoven with a layer of the machine side by being interwoven under at least one yarn in the machine side layer, in which paper machine fabric the number of warps in the layer constituting the machine side is larger than the number of warps in the layer constituting the paper side; and a pair of parallel bottom warps run in the weave by becoming interwoven with bottom wefts always in the same manner either at the same or a different stage, and the binder yarn enters and exits the machine side to bind the layers constituting the paper side and the machine side together by becoming interwoven under either bottom warp.
