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.

Abstract: A clothing, in particular a seam felt for a machine for producing a fibrous material web, in particular a paper, paperboard, tissue or pulp web, includes a base structure including or being formed of a two-layer laminate structure formed of one or more flat-woven fabrics. The laminate structure has MD threads which form seam loops at the two end sides of the base structure, and the two layers of the laminate structure are connected to one another by the seam loops. The clothing is made endless by connecting the end sides thereof by a seam. The seam is made by interengaging the seam loops of both end sides and introducing an insertion element. The diameter of the seam loops LD and the diameter of the associated MD threads MDYD have a ratio LD/MDYD of between 2.5 and 4, in particular between 2.7 and 3.6.

Abstract: A clothing for a machine for producing a fibrous web, especially a paper, cardboard, tissue or cellulose pulp web. The clothing has a basic structure with a top side and a running side as well as a nonwoven support at least on one side. The nonwoven support has a functional zone, which extends over more than 50 μm in the thickness direction of the clothing and which includes a first portion and a second portion of nonwoven fibers. The nonwoven fibers of the first portion are formed of, or include, a polyurethane, especially a thermoplastic polyurethane, while the nonwoven fibers of the second portion are a polymer material not including a polyurethane. The first portion makes up between 10 wt. % and 60 wt. %, of the functional zone. There is also described a method for production and a suitable nonwoven fabric.
