MULTI-LAYERED FORMING FABRIC WITH A TOP LAYER OF TWINNED WEFTS AND AN EXTRA MIDDLE LAYER OF WEFTS
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 (top) layer. This spacing imparts a d...

description | 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 (top) layer. This spacing imparts a desired non-uniformity in the web-supporting surface, thereby reducing diagonal fabric pattern. The forming layer wefts are vertically offset from the middle and wear side layer wefts, which are vertically stacked. This unstacked alignment reduces the caliper of the fabric and lowers the void wefts provide extra stability in the CD. |
