摘要： 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.

摘要： An extrusion die makes a structuring fabric which has structuring-beads resting on sublayer-beads. The extrusion die has a flat first surface and a flat second surface, the first and second surfaces contact each other along a contact line. The first and second surfaces are inclined with respect to each other. The first surface has a first nozzle of a pair of nozzles for extruding a sublayer-bead and the second surface has a second nozzle of the pair of nozzles for extruding a structuring-bead on top of the sublayer-bead. The first nozzle has a substantially rectangular shape and the second nozzle has a shape that resembles a square with all four side edges bulged inwardly. Both the first nozzle and the second nozzle are located in close proximity to the contact line. The first nozzle has a first symmetry axis that is perpendicular to the contact line.

摘要： A structuring fabric for use in a machine to produce a structured fiber web, such as a structured tissue fiber web, has a machine direction, a cross machine direction, and a thickness direction. The structuring fabric includes a woven base fabric with a web facing side and a machine side. A plurality of structuring beads of polymeric material are formed on the web facing side of the woven base fabric, the structuring beads being suitable to provide a visible structure to the fiber web that is produced on the structuring fabric. The structuring beads rest on an upper foundation surface of corresponding sublayer beads of polymeric material. The sublayer beads thereby provide a foundation for the structuring beads. There is also described a production method for producing such a structuring fabric.
