Abstract:
1. A paper machine fabric having a paper side surface and a machine side surface, the paper machine fabric comprising at least two separate layers made of at least four warp yarn systems woven in different manners and at least two weft yarn systems woven in different manners, the layers being bound together by means of a binder warp system, whereby the binder warp forms a portion of the surface of the paper side and to be interwoven with the layer of the machine side by being interwoven under at least one weft yarn of the machine side, in which paper machine fabric warp yarns of one warp yarn system, i.e. wandering warps, form a portion of a warp path formed by the binder warps so that the warp path is continuous at those points on the machine side where the binder warps constitute a part of the paper side structure, and are further arranged to run between the layers forming the paper side and the machine side at points where the binder warp binds the layers forming the paper side and the machine side together on the machine side.
