ABSTRACT:
A papermaking screen, especially for the sheet forming zone, has one paper side and one machine side with a first type of transverse yarns of the paper side and a second type of transverse yarns (25to40) of the machine side. The transverse yarns are woven with at least one type of longitudinal yarns (41to56). The longitudinal yarns (41to56) on the machine side within the machine-side pattern repeat bind two respective transverse yarns of the second type (25, 28; 31, 34; 37, 40). The division of the intersections for the longitudinal yarns is then improved, so that marks in the paper to be produced are prevented to the greatest extent possible.
