Abstract (en)
[origin: WO2020224835A1] The invention relates to a seamed felt for use in a machine for producing a tissue web, comprising a single-layer or multilayer base structure which has a textile structure with MD threads that form seam loops on both end-face edges of the base structure. The fabric can be made continuous by connecting the end-face edges of the fabric by means of a seam, and the seam can be produced by interlocking the seam loops of both end-face edges and introducing a plug element. The seamed felt additionally comprises at least one layer of nonwoven fibers. The invention is characterized in that the MD threads predominantly or as a whole have a diameter ranging between 0.25 mm and 0.45 mm, in particular between 0.3 mm and 0.35 mm, and the thread density of the MD threads is more than 37%, in particular between 37% and 45%. The invention additionally relates to a corresponding machine and method for producing a tissue web.
