Press arrangement for a machine for treating a fibrous pulp sheet. The press arrangement includes a shoe press roll having a flexible press sleeve, a mating roll having a mating roll axis, and a press nip extended in a run direction of the fibrous pulp sheet and formed between the shoe press roll and the mating roll. The press arrangement includes a non-rotating carrier substantially extending across a machine width inside the flexible press sleeve, a press unit including at least one press shoe supported on the non-rotating carrier via at least one associated force element. The press unit exerts a force against the flexible press roll sleeve. The flexible press sleeve is arranged to circulate around the non-rotating carrier and to be guided around the at least one press shoe in a press nip area. A portion of the flexible press sleeve, located outside of the press nip area, circulates in a substantially circular- cylindrical path around a sleeve axis. A center plane of a resulting force exerted by the press unit is positionally offset a distance in the run direction from a plane including the mating roll axis and the sleeve axis, and the press shoe is positioned substantially symmetrical to the plane including the mating roll axis and the sleeve axis.
