Abstract (en)
[origin: WO2019175076A1] The invention relates to a covering, in particular a seam felt for a machine for producing a fibrous material web, in particular a paper, paperboard, tissue or pulp stock web, comprising a basic structure including or consisting of a two-layer laminate structure formed of one or more flat-woven elements, wherein the laminate structure has MD threads which form seam loops at the two end sides of the basic structure, and the two layers of the laminate structure are connected to one another via the seam loops, and wherein the covering is made continuous by connecting the end sides thereof by means of a seam, and this seam is executed by engaging the seam loops of both end sides and introducing an insertion element. According to the invention, 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.
