Abstract
A forming fabric woven of synthetic continuous warp and weft filaments which is adopted for use with a papermaking machine. The forming fabric is formed with a support surface and a running surface with the running surface having abrasion resistant areas arranged along its length adjacent each of its edges. The abrasion resistant areas comprise abrasion resistant polyurethane impregnated to penetrate and bond with and about the warp and weft filament throughout the thickness of the forming fabric. The polyurethane forms protrusions on at least the running surface of the forming fabric.
