发明名称 Multi-layer fabric for paper-making
摘要 A multi-layer fabric for paper-making comprising at least two fabric layers A and B, each of which is formed by inter-weaving respective warps and wefts. An upper-most layer A is woven as a plain weave 1/1 except at binding points S1, S3 and is adapted to support a paper-web thereon. A lower layer B is positioned below the upper-most layer A, and formed by warps 3 and wefts 4, 4a, each of which have larger diameters than those of the upper-most layer A. The upper-most layer A and the lower-most layer B are bound by means of a part 1a of the warps 1 of the upper-most layer A being interwoven with a part 4a of the wefts 4 of the lower-most layer, or by means of separate binder threads 5 other than the warps or wefts being interwoven with the upper-most layer A and the lower-most layer B. At the binding points, a warp 1a of the upper-most layer which intersects with a weft 4a of the lower-most layer B or with a binder thread 5 is extended under three successive wefts 2a. A weft 2a of the upper-most layer A at the binding point S1 is extended above three successive warps 1, 1a, 1 of the upper-most layer A.
