Second pressing station includes shoe press roll located above a lower roll, and pressing plane of second pressing station is oriented essentially vertically or inclined at an angle &bgr;, which is a maximum of about 20° to vertical. The common lower felt is sufficiently dense to be essentially air impermeable even in its new state after moistening, and is sufficiently open to allow water through at pressures greater than about 5 bar. First and second upper felts are sufficiently open to allow air through in their moistened, uncompressed state, and pressing plane of first pressing station is oriented at an angle greater than angle &bgr;.
