The invention relates to a clothing (10) for a machine to manufacture or refine a fibrous web, in particular a paper, cardboard, or tissue web, comprising a substrate (40) and a grid structure (20) applied on the substrate (40), on which the fibrous web is transported when the clothing (10) is used as intended, wherein the grid structure (20) comprises a plurality of first elements (24), all of which aligned in a first direction, and a plurality of second elements (26), all of which aligned in a second direction, which is different from the first direction, wherein the first elements (24) penetrate the second elements (26), forming the grid structure (20), such that an underside of the first elements (24) facing the substrate (40) and an underside of the second elements (26) facing the substrate (40) are located in a common plane. In addition, the present invention relates to a method for producing such a clothing.

The object of the present invention is to provide an industrial fabric which exhibits an excellent surface smoothness and an excellent filtering ability, while at the same time reduces the generation of the hydration mark.

The industrial fabric of the present invention including at least one upper surface side fabric constituted by upper surface side warps and upper surface side wefts and at least one lower surface side fabric constituted by lower surface side warps and lower surface side wefts, said at least one upper surface side fabric comprising at least one concave binding yarn for pulling down including a portion where a single knuckle is formed and at least one convex binding yarn for pushing up located to be adjacent to said at least one concave binding yarn for pulling down, and said at least one convex binding yarn for pushing up passes under at least one or more said upper surface side warps or said upper surface side wefts woven with a portion where a single knuckle of said at least one concave binding yarn for pulling down is formed and includes at least two or more knuckles which are formed by passing over another upper surface side warp or another upper surface side weft located adjacent to said upper surface side warps or said upper surface side wefts.

A clothing for a machine for producing or processing a material web has a first and a second woven layer. The clothing has more first longitudinal threads than second longitudinal threads, but the number of first longitudinal threads is at most twice as large as the number of second longitudinal threads. Transverse threads of the second woven layer form contact floats on the machine contact side. Longitudinal threads of the first and second woven layer in each weaving repeat are arranged a first group and a second group. In the first group the longitudinal threads of the first and second layers are arranged precisely one above the other in the thickness direction of the clothing, while in the second group neither of two longitudinal threads of the first layer is arranged precisely above a single longitudinal thread of the second woven layer in the thickness direction of the clothing.

The invention relates to a paper machine fabric that consists of two layers, a paper-side layer and a wear-side layer. The paper-side layer consists of the top warps (1) and at least the binding top wefts (2), which have been adjusted to form a part of the paper-side surface, and the wear-side layer consists of the bottom warps (3) and bottom wefts (4). The binding top wefts (2) have been adjusted to bind the paper-side layer and the wear-side layer together. Each binding top weft (2) is adjusted so that it forms a continuous independent yarn path.

An industrial textile is provided, preferably suitable for use as a dryer fabric in a papermaking machine. The industrial textile has first and second surfaces and is defined by first and second systems of warp yarns interwoven with a system of weft yarns in a repeating pattern. In the repeating pattern, each of the warp yarns in the first system of warp yarns is interwoven with the system of weft yarns with a float on the first surface over at least 5 of the weft yarns, under 1 of the weft yarns, over 1 of the weft yarns, and under 1 of the weft yarns. Additionally, each of the warp yarns in the second system of warp yarns is interwoven with the system of weft yarns with a float on the second surface under at least 5 of the weft yarns, over 1 of the weft yarns, under 1 of the weft yarns, and over 1 of the weft yarns in the repeating pattern. Each of the warp yarns of the first system of warp yarns is stacked over a corresponding one of the warp yarns of the second system of warp yarns to form stacked pairs of the warp yarns.

An industrial two-layer fabric includes an upper layer fabric including upper side warps and upper side wefts and a lower layer fabric including lower side warps and lower side wefts, and the upper layer fabric and the lower layer fabric are bound by warps that function as binding yarns. The industrial two-layer fabric, warp knuckles are formed on a surface side, and each warp knuckle is formed by allowing a warp to pass over a single upper side weft; in a shaft adjacent to the warp knuckle, at least two other warp knuckles are arranged in a diagonal direction in a planar view; and the warp knuckles are sequentially arranged in such a way as to form a herringbone pattern on a surface layer side of the fabric.

A paper machine screen which is formed as a transverse thread-bound, multi-layer fabric. Binding transverse threads extend respectively both in an upper fabric layer and in a lower fabric layer and hereby bind the lower fabric layer to the upper fabric layer. The binding transverse threads form functional transverse thread pairs within the total repeat, the transverse threads of which alternately complete the first weave. In the total repeat, the functional transverse thread pairs in the upper fabric layer are arranged in groups of respectively two or more functional transverse thread pairs arranged directly one after another, when seen in a longitudinal direction.
