In a roll changer for a web-fed printing press describes a method for connecting a first web of material (01) with a second web of material (02), wherein the two material webs (01; 02) in each case to a roller (03; 04) are wound, wherein the roller (03) with the first web of material (01) a largely unwound length of the rest roll (03) and the roller (04) with the second web of material (02) a from the reel changer is held in reserve supply roll (04), whereby a drive unit (13) at least the rest roll (03) for unwinding the web of material (01) rotates, wherein a control unit (16) a rotational speed of the rest roll (03) is established, wherein at least the of the rest roll (03) progressively unwound and the second web of material (02) guided first web of material (01) in the time of the connecting of the two material webs (01; 02) is in motion, wherein a pressing element (21) the first material web (01), at least in the time of the connecting of the two material webs (01; 02) to the second web of material (02), characterized in that the control unit (16) in the continuous printing of the web-fed press the rotational speed..
