ABSTRACT:
A papermaker's fabric, usable in the forming section of a paper machine, has three layers of cross-machine-direction (CD) wefts. The forming layer wefts are grouped into pairs. This twinning of the top-layer wefts results in non-equal spacing in the forming layer. This spacing imparts a desired non-uniformity in the web-supporting surface, thereby reducing the fabric diagonal problem. One of the top-layer wefts in each pair is vertically stacked with the middle and wear side layer wefts. The other top-layer wefts in each pair are unstacked. This alignment increases the drainage properties of the fabric. The middle layer wefts provide extra stability in the CD.
