1. A paper machine mesh comprising:
an upper fabric layer having an outer side which forms a paper side of the paper machine mesh, said upper fabric layer including a plurality of upper transverse threads; and
a lower fabric layer comprising a plurality of longitudinal threads and, woven therewith, a plurality of lower transverse threads extending transverse to said plurality of longitudinal threads,
wherein said upper fabric layer includes an upper weaving pattern, which is repeated in a plurality of upper repeats, comprising weaving of said plurality of longitudinal threads with said plurality of upper transverse threads,
wherein said plurality of longitudinal threads include, through weaving with said plurality of upper transverse threads, a plurality of upper longitudinal thread runs arranged side by side in a transverse thread direction with a plurality of longitudinal thread lifts and a plurality of longitudinal thread lowerings of said upper weaving pattern, wherein each of said plurality of upper longitudinal thread runs extends over a length of each of said plurality of upper repeats in a longitudinal thread direction,
wherein each of said plurality of longitudinal thread lifts comprises respective said plurality of longitudinal threads respectively weaving with said plurality of upper transverse threads continually crossing respective said plurality of upper transverse threads on said outer side of said upper fabric layer,
wherein each of said plurality of longitudinal thread lowerings comprises respective said plurality of longitudinal threads respectively weaving with said plurality of upper transverse threads continually crossing respective said plurality of upper transverse threads between said upper fabric layer and said lower fabric layer, and
wherein said plurality of longitudinal thread lifts and said plurality of longitudinal thread lowerings of said upper weaving pattern are arranged irregularly distributed in said plurality of upper repeats.
