A valve assembly for the sealed reception of an elongated object is provided. In that the longitudinal yarns on the machine side within the machine-side pattern repeat bind two respective transverse yarns of the second type, the division of the intersections for the longitudinal yams is improved, so that marks in the paper to be produced are prevented to the greatest extent possible. The method further includes polishing on the second layer of isolation dielectric to remove the second layer of isolation dielectric from the first material.
