A roll changer for a web-treating or web-processing machine, or a web-fed printing press is provided. The roll changer includes a first roll arm ( 4 ) with a first axle journal ( 8 ), which can be pivoted about a pivot axis ( 3 ), and a second roll arm ( 5 ) with a second axle journal ( 8 ), which can be pivoted about the pivot axis ( 3 ) together with the first roll arm ( 4 ). The axle journals ( 8 ) form a rotary mount for a web roll ( 10 ) taken up between the roll arms ( 4, 5 ). A first stripper ( 9 ) is assigned to the first axle journal ( 8 ) and can be moved in relation to the first axle journal ( 8 ), in order to strip the web roll ( 10 ) from the first axle journal ( 8 ). A drive ( 11 a -11 d) is provided for pivoting the roll arms ( 4, 5 ) and moving the first stripper ( 9 ). A control device ( 12 ) controls the drive ( 11 a -11 d) for a manual removal of a web roll ( 10 ) so that the web roll ( 10 ) mounted on the axle journal ( 8 ) is stripped by the first stripper ( 9 ) from the first axle journal ( 8 ), while it remains on the second axle journal ( 8 ).
