摘要

A paper or cardboard machine press section includes sequentially arranged first, second, and third presses each having opposed first and second press members forming a press nip therebetween. A press felt is arranged in a loop and passes through the press nip of the third press. An impermeable transfer belt is arranged in a loop to receive the web from the second press and transfer it to the press felt of the third press. A wet calender defining at least one roll nip is provided between the second and third presses, and the web and the transfer belt pass through the roll nip of the wet calender. In a preferred embodiment, the roll nip of the calender is formed by a smooth press roll of the second press arranged outside the loop of the transfer belt, and a guide roll that is arranged within the loop of the transfer belt.
