The roll stand has swivel arms and is part of a web-fed rotary printing press which uses the printing paper rolls. The traveling platform is equipped with lifting elements acting together in pairs, which permit aligning of the paper rolls with a paper roll bearing axle of the roll stand while allowing paper rolls of different diameters and widths to be brought for clamping between pairs of the swivel arms of the roll stand or to be removed from the swivel arms of the roll stand.
