Multi-layer papermaker's forming fabric with alternating paired and single top CMD yarns
Abstract:
A papermaker's fabric comprises a series of repeat units. Each of the repeat units comprises: a set of top MD yarns; a set of top 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 CMD stitching yarns interwoven with the top and bottom CMD yarns to bind the top and bottom fabric layers together. The stitching yarns are arranged in pairs. The top CMD yarns are arranged in an alternating pattern in which first (a) a single top CMD yarn is positioned between adjacent pairs of stitching yarns, then (b) two top CMD yarns are positioned between adjacent pairs of stitching yarns.
