The press has a framework including two side frames 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 upstream of the press nip and a second vertical column downstream of the press nip. The upper roll is carried by a brackets extending between the upstream and downstream vertical columns. The brackets have bevelled ends that co-operate with inclined surfaces of plate members on the vertical columns.
