Abstract
The present invention is directed to the problem which occurs when papermakers' fabrics are woven in a pattern in which the various warp of the pattern require different warp yarn lengths, i.e. unequal sew-up. The invention solves the problem by providing a monoplanar papermakers' fabric formed of warp and weft yarns interwoven in a repeating sequence of first and second adjacent patterns which alternate along the warp. The warp of the second weave pattern have a sequence of numbers of interlacings which is the reverse of the sequence for the first weave pattern so that the total number of interlacings in the combined first and second weave patterns is equal for all warp yarns.
