<p>The invention relates to an apparatus for separating perforated tubular web sections, having an advancing mechanism and a tearing-off mechanism. These have in each case on both sides of the tubular web to be separated opposing rollers or rolls, over which endless conveyor belts run, the rolls of the tearing-off mechanism being movable in the direction of the tubular web by means of a control element. To prevent any slipping of the web in the advancing mechanism during the tearing off of tubular web sections, it is provided that the advancing mechanism also has a control element by means of which the rolls of the advancing mechanism are adjustable in the transverse direction of the tubular web to increase the contact pressure acting on the tubular web and that this control element of the advancing mechanism is synchronised with the control element of the tearing-off mechanism. <IMAGE></p> |
