Double-layer clothing for the sheet-forming section of a papermaking machine

Abstract From the Canadian patent

A double-layer fabric for the sheet forming section of a papermaking machine which is referred to as a sheet forming fabric or a dewatering fabric consists of an upper layer of transverse threads and a lower layer of transverse threads which are interwoven with a single system of longitudinal threads. Successive transverse threads of the lower layer form pairs and within each pair the lowest points of the transverse thread float are in alignment. The lowest point of the float of the one transverse thread of a pair is offset from the center of the float in the direction opposite the direction in which to the lowest point of the float of the other transverse thread is offset.
