Abstract

A clothing, in particular a seam felt for a machine producing a fibrous material web, in particular a paper, paperboard, tissue or pulp web, includes a base structure including or formed of a two-layer laminate structure formed of one or more flat-woven fabrics. The laminate structure has MD threads forming seam loops at 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 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.
