Abstract
A papermaker's fabric includes a plurality of repeat units of interwoven yarns, each repeat unit comprising: a set of top MD yarns; a set of top CMD yarns interwoven with the top MD yarns; a set of bottom MD yarns; and a set of bottom CMD yarns interwoven with the bottom MD yarns. In interweaving with the top CMD yarns, some of the top MD yarns include a segment in which the top MD yarn passes below a subset of three consecutive top CMD yarns. Each of the bottom MD yarns forms a knuckle over one of the three top CMD yarns of the subset that a top MD yarn located immediately thereabove passes below. The set of bottom CMD yarns includes at least twice as many yarns as does the set of bottom MD yarns.
