<p>In a paper machine, a twin-wire wire section comprising a first wire loop and a second wire loop, of which the first wire loop transports forward the web that is being formed, a common run of the wire loops with an ascending main direction in the direction of travel of the web, two forming rolls means substantially one above the other lapped by the common run of the wires, a breast roll and a headbox, characterized in that at least the first forming roll means in the direction of travel of the web is a lower roll means and has a solid shell without any suction possibilities, the dewatering taking place at least to a substantial extent in a direction outwardly away from the forming roll means, the common path curving first in one direction about the lower forming roll means, then being substantially straight and tangential to both of the forming roll means, and then curving in an opposite direction around the upper forming roll means, so that the common path is of a substantially S-shaped configuration.</p> |
