Abstract

In a single-layer papermaking woven fabric or more than three shafts having an extended running surface formed from long crimped primary wefts, auxiliary wefts each having a smaller diameter than that of primary wefts are each disposed between each of primary wefts. Every auxiliary weft is placed on warps at portions extended from the paper side of where warps are primary weft to the running said of the succeeding primary weft or at portions where warps are extended from the running side of a primary weft to the paper side of the succeeding primary weft. Each of said auxiliary wefts is woven into texture of the fabric at least once in a repeating unit by a warp to thereby complete the repeating unit. To this end, the auxiliary wefts are disposed in recesses which will otherwise make appearance on said papermaking surface at locations corresponding to the portions of the warps extending from one of the papermaking surface and the running surface of the fabric toward the other in order thereby to form a smooth papermaking surface.
