Abstract: A sieve for the wet-end section of a paper machine is described, in which the sieve has been compressed by at least one of increased temperature, pressure and/or moisture. Such a treatment leads to a sieve which has at least one side wherein the thread floats and knuckles are reshaped and the sieve presents at least one substantially flatter surface for the production of paper. This process does not cause any physical damage to the surface of the sieve, as current techniques of abrasively polishing the surface do, and therefore leads to cloths with improved properties and lifetimes.

Abstract: A papermaking forming fabric includes a series of repeat units, wherein each repeat units includes: a set of top machine direction (MD) yarns; a set of top cross-machine direction (CMD) yarns interwoven with the top MD yarns to form a top fabric layer; a set of bottom MD yarns; a set of bottom CMD yarns interwoven with the bottom MD yarns to form a bottom fabric layer; and a set of stitching yarns interwoven with the top and bottom fabric layers. The bottom MD yarns and bottom CMD are woven such that floats formed by the bottom CMD yarns under the bottom MD yarns are at least 1.8 mm in length. A first ratio of top MD yarn coverage area to bottom MD yarn coverage area is less than 0.5, and a second ratio of bottom CMD yarn cross-sectional area to bottom MD yarn cross-sectional area is greater than 2.0.
