Abstract
A single layer papermaking machine forming fabric which is woven from a single layer of warps interlaced with primary wefts, secondary wefts, and, if desired, tertiary wefts. The secondary and tertiary wefts are located between the primary wefts. The fabric is woven in a first pattern which repeats once in N sheds, and N is at least 10. The primary, secondary, and, if present, tertiary weft are woven to second, third, and, if present, fourth patterns in a lower number of sheds and which repeat at least twice within the first pattern. This weave provides a forming fabric having good first pass retention, good drainage properties, reduced wire mark, good fabric height and good release characteristics. In certain pattern combinations a forming fabric can be woven exhibiting a level of visual discontinuity or randomness in the paper side face.
