ABSTRACT:
A method of weaving on a loom a multilayer paper forming fabric in an eight warp repeating pattern. The weaving is controlled to produce uniform drainage channels throughout the forming fabric. The paper forming fabric is formed to have a weft yarn dominant paper support surface and a weft yarn dominant running surface. The loom includes a reed which has a plurality of reed teeth which form dents. A single layer of side-by-side warp yarns are arranged through the dents of the reed so that each warp yarn engages with at least one reed tooth. A weft yarn of a first layer of weft yarns is woven with the warp yarn to form the weft dominant paper support and a weft yarn of a second layer of weft yarns is woven with the warp yarn to form the weft dominant running surface. Each pick of weft yarn of the first and second layers of weft yarn is beaten-up by the reed to be substantially evenly spaced throughout said paper forming fabric by controlling each warp yarn during beat-up with at least one reed tooth and by controlling each weft yarn adjacent each formed warp knuckle. The process produces uniform and consistent crimps which provide for uniform drainage channels throughout.
