1. A paper machine mesh comprising:
an upper fabric layer including an upper fabric layer outer side which forms a paper side of the paper machine mesh;
a lower fabric layer including a lower fabric layer outer side which forms a machine side of the paper machine mesh; and
a plurality of tie threads extending in a longitudinal thread direction which connects said upper fabric layer and said lower fabric layer to each other,
wherein said upper fabric layer comprises at least said plurality of tie threads and, woven therewith, a plurality of upper transverse threads extending transverse to said plurality of tie threads,
wherein said lower fabric layer comprises at least said plurality of tie threads and, woven therewith, a plurality of lower transverse threads extending transverse to said plurality of tie threads,
wherein each of said plurality of lower transverse threads is held respectively by several of said plurality of tie threads in that each of said several of said plurality of tie threads continually crosses respective said plurality of lower transverse threads on said outer side of said lower fabric layer, wherein at least some of said plurality of tie threads holding respective said plurality of lower transverse threads are separated from each other by at least one of said plurality of tie threads not holding respective said plurality of lower transverse threads in that respective said plurality of lower transverse threads continually crosses said at least one of said plurality of tie threads not holding respective said plurality of lower transverse threads on said outer side of said lower fabric layer, and
wherein several of said plurality of lower transverse threads include an identical number of said at least one of said plurality of tie threads not holding respective said plurality of lower transverse threads arranged respectively between consecutive said plurality of tie threads holding respective said plurality of lower transverse threads.
