The press section includes a press nip (10) and two fabrics (14, 15) arranged to travel through it. In addition, the press section includes a suction roll with a suction apparatus (21) fitted after the press nip (10). The suction apparatus (21) includes at least one suction case (24, 24'), which is arranged in a closing throat (25) and/or an opening throat (25') formed by one of the fabrics (14, 15) and the suction roll (18). The suction case (24, 24') is also arranged before and/or after the suction roll (18) in the edge of the fabric (15) in order to create a suction effect in a narrow edge area of the web (13).
