The machine also includes at least one belt that is water-permeable and water-absorbent and that is adapted to guide the fiber material web through the press nip, and at least one suction device located ahead of the elongated press nip, relative to a belt travel direction. The at least one belt is guided over the at least one suction device. The process includes guiding the at least one belt over the at least one suction device and suctioning the at least one belt, such that moisture is removed from the at least one belt, and guiding the fiber material web and the suctioned at least one belt through the extended press nip.
