A cover is provided with a drive that can move the cover. A control unit is provided to control the drive for the cover. The cover is closed in a first operational state and is open in a second operational state. The roll of material, that is supported by the roll changer, has a first rotational speed or web speed when the cover is in the first, closed operational state. In the second, cover opened, operational state, the roll of material also has a second rotational or web speed which is greater than zero. A method for controlling a device on a roll changer is also disclosed.
