Flat woven carpet comprises parallel warp ends, which have different diameters and run at specific distance from each other to form ribbed surface

摘要

The warp ends are woven together with transverse picks, which run alternatingly over and under a warp end. An additional warp end with a smaller diameter than the others runs between the rest of the warp ends. The picks have different diameters and are arranged in such a way that a thick pick runs over and a thin pick runs under the warp ends; only a thin pick runs over the thinnest picks.
