Abstract (en)
[origin: WO2006034596A1] 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; 15 1, 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.
