Abstract
A papermachine fabric for the production of tissue paper or porous batts has a two layer fabric comprised of a fine upper fabric layer and a coarser lower fabric layer. Both fabric layers have a large open area. The two fabric layers are firmly interconnected so that the upper fabric layer exhibits depressions at the sites of interweaving which are distributed in the manner of a pattern. The papermachine fabric is especially suited as an embossing fabric for after drying the paper web coming from a sheet forming fabric or as a second sheet former of a twin wire former.
