  • Publication number: 20240068166
    Abstract: A fabric for a machine for producing a fiberweb, the fabric including a woven base structure including a first base element and a second base element, wherein the first base element includes a first flat woven base material and the second base element includes a second flat woven base material, wherein the first flat woven base material has a length of twice a length of the fabric and is folded in a middle, creating a first two-ply element and a first fold, wherein the second flat woven base material also has a length of twice the length of the fabric and is folded in a middle, creating a second two-ply element and a second fold, and wherein the first base element and the second base element is arranged so that at least one ply of the first two-ply element is positioned between plies of the second two-ply element.

  • Patent number: 11280048
    Abstract: A fabric clothing, in particular a press felt, for use in a machine for producing a fibrous web, contains a woven fabric strip having interwoven longitudinal threads and cross threads, as well as having a first and a second longitudinal end. The two longitudinal ends of the woven fabric strip are connected to one another in a connection zone. Provision is made that the two longitudinal ends are welded to one another by a transmission welding, in particular by a laser transmission welding.

  • Patent number: 9982388
    Abstract: A fabric for a machine to produce a fiber web, especially a paper-, board-, tissue- or pulp web, is formed of a flat woven base material having a top side and a bottom side, two terminal ends separated in a machine direction, folds formed in the flat woven base material being separated in the machine direction by the folding defining an inside between the two folded layers and an outside. The two terminal ends are located under the bottom side surface, wherein the two terminal ends one of are adjacent to each other or overlap each other, seam loops located at the folds characterized in that the fabric further has one, two or more sheet-like plies. Also a method to produce a fiber web, especially a paper-, board-, tissue- or pulp web is carried out with a machine that is provided with at least one such novel fabric.
