The invention relates to a device, for the lateral separation of paper webs, comprising: (I) a paper introduction region with at least one driven web supply roller, (II) a buffer region, in which the web is prepared for the discontinuous forward motion, (III) a cutting device, with a cutting means and (IV) a paper lead-off region with discontinuous web forward motion, comprising at least one tube group ( 120; 150 ) with two tubes ( 121, 122; 151, 152 ), which may be moved relative to at least one third tube ( 123; 153 ) of the group ( 120; 150 ) perpendicular to the web. The tube group ( 120; 150 ) is arranged between the paper introduction region with the tubes ( 140, 142 ) and the discontinuously driven paper web ( 130 ) in order to form a turning web loop of varying length. The length as determined by the separation between the tubes of the tube group is regulated by a controller, in connection with the driven web supply roller and the discontinuous web forward motion.
