Abstract
A roll changing carriage can be displaced transversely with respect to the strip rolling stand and a removal crossbar is provided for the removal of the set of backup rolls. In order to shorten the roll changing times and to automate the changing of the rolls, the removal crossbar can be positioned on the roll changing carriage and is provided with wheels on which the removal crossbar can be moved out of the roll changing carriage on guide rails running parallel to the rolls into the strip rolling stand on the intermediate roll rails, and can be pulled out of the strip rolling stand together with the set of backup rolls.
