As the speed of the formation of paper web increases fabrics become tighter. This greater tightness poses challenges to the fabric such as dimensional stability. The present application addresses such issues. In particular, a paper machine fabric having a paper side surface and machine side surface is described. 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 are bound together by means of a binder warp system, whereby the binder warp is arranged to complement the paper side surface and to be interwoven with a layer of the machine side surface by being interwoven under at least one weft yarn of the machine side surface. The warp yarns of one warp yarn system, i.e. wandering warps, are arranged to complement a warp path formed by the binder warps so that it is continuous at those points on the machine side surface where the binder warps constitute a part of a structure of the paper side surface. The wandering warps are further arranged to run between the layers forming the paper side surface and the machine side surface at points where the binder warp bends the layers forming the paper side surface and the machine side surface together on the machine side surface. |
