ABSTRACT:
A multi-layer on-machine-seamable press fabric having a single or double layer weave over the seam loops where the warp ends are not normally woven with CD yarns. The CD yarns woven into the layer(s) over the seam loops provide the fabric with substantially similar characteristics—including caliper and water permeability—in the seam area as in the remainder of the fabric. Hence, the press fabric provides a solution to the problem of non-uniformity in the seam area, which often results in sheet marking.
