ABSTRACT:
A method for making a woven dryer fabric having different permeabilities in different sections across its width to control the moisture profile of a web being conveyed through the dryer section of the papermaking machine is disclosed. Additional cross machine yarns are interwoven only over a selected distance or distances across the fabric in the cross machine direction. The non-interwoven segments of the additional cross machine direction yarns form surface floats which are subsequently removed by shearing.
