The aim of the invention is to enable the time required for a back-up roll change to be reduced and the back-up roll change to be simplified. To this end, the roll-changing stand (8) comprises two roll-receiving regions (13, 14) that have an especially U-shaped cross-section and are arranged at a distance from each other in the roll direction of the roll stand, said regions each comprising both bearing surfaces (15, 16) for receiving work rolls (4a, 4b) and bearing surfaces …
