ABSTRACT:
A papermaking wire cloth, especially for the sheet forming zone, includes a paper side (12) and a backing side (14). The wire cloth is formed out of at least one type of transverse threads (16, 18) which are interwoven with at least one type of longitudinal threads (20). The threads together form repeats (A-H) and at least two different types of crossing (22, 24). The longitudinal threads (20) are alternated within the respective repeat (A-H) on the backing side (14), forming the other type of intersection (24). The transverse threads (18) on the backing side (14) are held on their outer side (26) which faces the paper side (12), by at least two longitudinal threads (20) within the repeat (A-H) on the backing side (14). Maximum fibre support is achieved on the paper side accompanied by little marking of the upper side as the points of alternation or intersections are evenly distributed.
