The invention relates to pressing pressed articles (PT) from wet pulp (MM), the pressing being carried out by means of a press chamber (2) and a piston (5) arranged therein. The invention is characterized by pressing wet pulp (MM) in the press chamber (2) by the piston (5) whose outer surface (11) in the direction of movement thereof is substantially even and the perimeter of the outer surface (11) thereof is smaller than the perimeter of a corresponding inner surface (12) of the press chamber (2) such that liquid (N) being separated from the wet pulp (MM) in connection with the pressing is discharged from the pressed articles via a flow channel (9) provided between the outer surface (11) of the piston (5) in the direction of movement thereof and the corresponding inner surface (12) of the press (2).
