Abstract: A single layer woven fabric for paper-making, in which at least a pair of two successive knuckles in the paper-making side at an interval of one warp, and at least one crimp in the running side form a plain weave structure. The knuckle be formed by allowing a weft to pass over one warp, to pass under one adjacent warp, and then to pass over the one warp. The crimp be formed by allowing a weft to pass under not less than three successive warps. The plain weave structure is formed by binding two or three wefts constituting a group which in turn constitutes a repeating unit and by placing the combined group, in the direction of wefts, so that the knuckles of wefts in the paper-making side are placed successively at an interval of one warp. The placement of the wefts group is made by shifting the group as the whole successively by a distance corresponding to an odd number of the warp.

Abstract: A fabric for use in paper machines which forms a repeating design unit with fourteen yarns or more for each of warps, upper wefts and lower wefts is shown. The fabric starts the repeating design unit from a point of the lower weft being interwoven with the warp, wherein the lower wefts are interwoven with the warp once or twice, adjacent two upper wefts are interwoven with the warp twice, the numbers of wefts disposed between positions of the warp interweaving the lower weft and the adjacent two upper wefts are equal to each other, and the warp travels between the upper and lower wefts in a substantially linear manner between two positions of the adjacent two upper wefts being interwoven with the warp.

Abstract: In a single-layer paper making woven fabric of more than five shafts, auxiliary wefts each having a smaller diameter than that of the primary wefts are disposed between each of the primary wefts. Each of the auxiliary wefts is woven twice into a repeating unit of a texture by a warp. Each auxiliary weft is placed over at least two other warps extending above two adjacent primary wefts. The auxiliary wefts are pushed or urged upwardly thereof by these at least two other warps in order to form a flat paper making surface of the fabric, whereby wire marks on a paper are reduced.
