PAPERMAKER'S FORMING FABRIC

摘要

The bottom machine direction yarns (122-140) and the bottom cross machine direction yarns (142-180) of a triple layer fabric (20) are interwoven in a series of repeat units in which the bottom machine direction yarns (122-140) to form bottom machine direction knuckles, and in which pairs of bottom machine direction yarns (142-180) separated from one another by one bottom machine direction yarn form bottom machine direction knuckle pairs under a common bottom cross machine direction yarn. Each bottom machine direction knuckle pair forms two imaginary diagonal lines with a nonadjacent bottom machine direction knuckle pair such that each bottom machine direction knuck le pair in the diagonal lines is offset by two cross machine direction yarns an d one bottom machine direction yarn.
