Patent ID: 7637291

Claim:
A paper machine mesh, comprising: an upper fabric layer including a plurality of upper longitudinal threads; a lower fabric layer including an outer side; a plurality of binder threads joining said upper and lower fabric layers, said lower fabric layer including said plurality of binder threads, a plurality of lower transverse threads, and, woven therewith and extending transversely thereto, a plurality of lower longitudinal threads, said lower fabric layer having a weaving pattern which is repeated in a plurality of lower repeats, said plurality of binder threads being arranged respectively in a plurality of binder thread pairs, said binder threads of each said binder thread pair being interchangingly woven with said plurality of upper longitudinal threads and said plurality of lower longitudinal threads, each said binder thread pair including two sides, each said binder thread pair being flanked on each of said two sides respectively by one said lower transverse thread which is thereby a flanking lower transverse thread, each of said two flanking lower transverse threads corresponding to a respective said binder thread pair being woven in a periodic sequence with said plurality of lower longitudinal threads as follows: i) said flanking lower transverse thread continually crosses a plurality of directly consecutive said lower longitudinal threads on said outer side of said lower fabric layer, and ii) said flanking lower transverse thread continually crosses a respective said lower longitudinal thread between said upper and lower fabric layers and forms a thread knuckle, wherein within each said lower repeat: i) each said binder thread of each said binder thread pair forms together with respective ones of said plurality of lower longitudinal threads at least one tie segment, each said tie segment being formed in that each respective said binder thread of each said binder thread pair continually crosses at least two directly consecutive said lower longitudinal threads on said outer side of said lower fabric layer, and ii) each said tie segment of each said binder thread pair is arranged relative to respective said lower transverse threads flanking each said tie segment such that: a) said two flanking lower transverse threads corresponding respectively to each said binder thread pair continually cross on said outer side of said lower fabric layer at least the same said lower longitudinal threads which together with said binder threads of said binder thread pair form each said tie segment, b) one of said two flanking lower transverse threads forms respectively one said thread knuckle with a respective one of said lower longitudinal threads which directly precedes a corresponding said tie segment, and c) the other of said two flanking lower transverse threads forms respectively one said thread knuckle with a respective one of said lower longitudinal threads which directly follows a corresponding said tie segment.
