<p>A folding device (100) for folding a paper web (102) in the longitudinal direction includes a first rolling device (104) adapted to receiving the paper web from a supplying device (110). A fold-creating means (106) is adapted to create at least one fold along the paper web. A fold-pressing means (108) is adapted to press together portions of the paper web which are separated by the fold. A second rolling device (109) is adapted to receive and guide the folded paper web out from the folding device to a receiving device (112). At least a first and a second motor (114, 116) are connected to a control unit and are adapted to drive the paper web through the folding device and to maintain a predetermined tension in the paper web.</p> |
