Abstract
A wet web transfer belt for a closed draw papermaking machine is provided with a rough surface to allow easy release of a wet web. The rough surface is obtained easily, and with reliable quality, by forming the web-contacting side of a batt layer from a welded layer of meltable fiber. A filler is included in the surface portion of the welded layer, extending from the surface at least part way into the welded layer, thereby facilitating the production of projections and concavities which provide the rough surface, and resulting in a wet web transfer belt of stable quality.
