Abstract

A composite papermaking fabric including an upper fabric upon which a fiber suspension will be deposited for producing paper and a lower fabric or running surface being driven by the papermaking machine. The upper and lower fabrics are connected by binding threads. Use of separate, independent binding threads or binding threads which are only a part of the upper layer is replaced by the interweaving of fabric-born threads which are an integral part of the lower fabric and fabric-born threads which are an integral part of the upper fabric. Relative slippage between the upper and lower fabric layers is eliminated or decreased and the strength of the connection is increased. The marking of the paper is decreased. The fabric-born threads of one fabric layer cross the fabric-born threads of the other after at least one length of weave pattern.

Dependent claims

A composite papermaking fabric comprising an upper fabric having an upper weave pattern and a lower fabric having a lower weave pattern superimposed on one another and connected by binding threads which are fabric-born threads forming an integral part of the upper and lower fabric weave patterns, wherein a first binding thread which is interwoven with cross direction extending threads of the upper fabric for at least one length of the upper fabric weave pattern is vertically stacked over a second binding thread which is interwoven with cross direction extending threads of the lower fabric for at least one length of the lower fabric weave pattern, and said first binding thread is crossed over said second binding thread, and said first binding thread is interwoven with the cross direction extending threads of the lower fabric for at least one length of the lower fabric weave pattern vertically stacked below said second binding thread which is interwoven with the cross direction threads of the upper fabric for at least one length of the upper fabric weave pattern.
