Abstract
In the device disclosed, a paper web is carried on a belt and stabilized by an underpressure produced by a box opposite the roll, the paper web being sucked by the underpressure against the belt. Located in the box, immediately following the underpressure zone, may be a pressure zone which assists to transfer the paper web to the roll. In an alternative embodiment, a fan can be avoided. Instead the air entrained by the rapidly running belt is deflected by a wedge-shaped deflector and passed over a slit to generate an underpressure inside the box.
