ABSTRACT:
The invention relates to a press for the dewatering of fiber material webs with two press elements, the pressing surfaces of which can be pressed towards one another while forming a press gap, with the fiber material web being guided through the press gap together with at least one dewatering band extending between the fiber material web and in each case one of the press elements. Each dewatering band is separated at the press gap outlet from the fiber material web and is guided at at least one side of the fiber material web in a section following the press gap over a predeterminable angular region of the respectively associated press element. A short suction zone can be variably designed in all embodiments so that a reverse moistening of the fiber material web through the dewatering band after departing from the press gap is at least partly prevented and a guide roll for the fiber material web following the press gap can be arranged as close as possible to the press gap.
