Abstract
A woven belt for a machine for producing web material, in particular forming mesh, including at least two woven layers with warp threads extending in a belt longitudinal direction and weft threads extending in a belt transverse direction, wherein a first of the woven layers provides a web material contact side and a second of the woven layers provides a machine contact side and the woven layers are joined together by tie warp threads, wherein the first woven layer is woven with at least 26 different warp runs, the structure-forming warp threads woven into the first woven layer and the weft threads of the first woven layer having a maximum floating length of 3 in relation to each other, wherein, when the tie warp threads for providing structure-forming tie thread pairs are arranged in pairs relative to each other so that where a tie warp thread of a respective structure-forming tie warp thread pair is integrated into the first woven layer then the other tie warp thread of this structure-forming tie warp thread pair is integrated into another woven layer, then changeover points at which the tie warp threads of the structure-forming tie warp thread pairs cross each other for switching between the first woven layer and the other woven layer are distributed irregularly within a warp/weft repeat, or wherein, when the tie warp threads are integrated into the first woven layer with no structure-forming effect and tie onto tie-on points over weft threads of the first woven layer, then the tie-on points within a warp/weft repeat are distributed irregularly.
