ABSTRACT:
A paper machine fabric comprising at least two separate layers formed using at least two separate yarn systems: one constituting the paper side and comprising machine direction and cross machine direction yarns and the other constituting the machine side and comprising machine direction and cross machine direction yarns, the yarn systems being arranged to form independent structures in both directions of the fabric. The structures are bound together with binder yarns, a binder yarn being arranged to form part of the 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. The number of machine direction yarns in the layer constituting the machine side is larger than the number of machine direction yarns in the layer constituting the paper side.
