ABSTRACT:
A press section of a paper machine includes a pick-up roll, a take-off felt looping about at least the pick-up roll and a connected first pressing element, and a counter element assigned to the first pressing element. The counter element and the first pressing element define a first press unit. A first pressing felt loops about at least the counter element of the first press unit and a second pressing element with a smooth surface. The second pressing element forms a second press unit with the first pressing element. The press section also includes a smooth press belt partially looping around a portion of the second pressing element, a third pressing element looped about by the smooth press belt, and a third counter element assigned to the third pressing element. The third counter element and the third pressing element form a third press unit. A third pressing felt loops about at least the third counter element. A take-off device disposed downstream the third pressing unit with respect to a direction of conveyance of a paper web through the press section is disposed against the smooth press belt.
