A top roll lifting arrangement for a roll press in a press section of a papermaking or boardmaking machine where the roll press includes a top roll (1) and a bottom roll (2), the rolls being opposed and parallel and having main axes defining a press plane (P) and forming between them a press nip (N ). The press has a framework including two side frames (6) in parallel relationship to each other, one located on the drive side of the machine and the other one on the tender side of the machine. Each side frame has a first vertical column (7) upstream of the press nip and a second vertical column ( 8) downstream of the press nip. The upper roll (1) is carried by a bracket (10) extending between the upstream and downstream vertical columns (7, 8). The brackets have bevelled ends (33) that co-operate with inclined surfaces (32) of plate members (31) on the vertical columns.
