Abstract: 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.

Abstract: The invention relates to an arrangement (1) for conveying of sheets (2a, b), comprising upper and lower receiving rolls (3, 4), an upper belt element (5) and a receiving surface (6). The belt element (5) extends in a region above the receiving surface (6). The sheets (2a, b) are conveyed in a substantially horizontal direction of movement (7) towards the receiving rolls (3, 4), which receiving rolls (3, 4) during rotation move the sheets (2a, b) one after another between and past the receiving rolls (3, 4), during which the respective sheet (2a, b), after passing between and past the receiving rolls (3, 4), are situated between said receiving surface (6) and upper belt element (5). The sheets (2a, b) between the upper belt element (5) and the receiving surface (6) are placed on one another such that a rear edge (8) of a sheet (2a) passing through and between the receiving rolls (3, 4) is overlapped by a front edge (9) of a following sheet (2b).
