A press arrangement and process for treatment of a fibrous material web. The press arrangement includes a press shoe unit, a press suction roll, at least one first press nip elongated in a web travel direction, the first press nip being formed between the shoe press unit and the press suction roll, the press suction roll being arranged as a web pick-up roll, at least one second press nip elongated in the web travel direction and positioned downstream of the first press nip relative to the web travel direction, at least first and second felts being arranged to be guided through the at least one first press nip, the first felt being arranged to loop around the press suction roll to pick-up the web from a screen belt whereby the web is transferred from the screen belt to the first felt, wherein the web is guided to the first press nip by the first felt and the web is guided through the first press nip between the first and second felts. The process provides for treating the web in an arrangement that includes first and second felts, a web belt, a web pick-up roll, a shoe press unit, a center suction roll, an additional mating roll, a dryer screen, and a dryer cylinder, and includes guiding the web and the first felt to the web pick-up roll, the web being supported on the web belt, engaging the web with the second felt, feeding the web, the first felt, and the second felt through a first press nip which is elongated in a web travel direction, the first press nip being formed by the shoe press unit and the web pick-up roll, disengaging the first felt from the web, wrapping the web and the second felt around a portion of the center suction roll disposed between the first and second press nips, feeding the web and the second felt through a second press nip which is elongated in the web travel direction, the second press nip being formed by the shoe press unit and the additional mating roll, disengaging the second felt from the web, and transferring the web to the dryer screen for delivering the web to the dryer cylinder.
