Zusammenfassung:The invention relates to a press section for a paper machine having at least one press unit, as well as sections connected after the press section, e.g. a second press unit or a drying section, furthermore having wires or felts (4, 5) which are guided through the press nips and having deflection rolls (7, 10) connected after the press nip, which guide the respective wire or felt away from the paper web, and having a suction pipe (9), which is arranged between the press nip of the first press unit and the first deflection roll. In such press sections having after-connected units, the transfer region is particularly problematical and, to be specific, with respect to the proper transfer of the tail or of the paper web, likewise also, however, from the point of view of optimal dewatering. According to the invention, the two deflection rolls (7, 10), are movable in the transfer region such that they can be moved away from or closer to the paper web.
