A pressing device having an endless conveyor which includes conveying elements connected to each other to form and endlessly revolving track. Adjacent conveying elements are pivotally connected together via pins forming pivot axes. A press roller is provided in a pressing zone to apply pressure to the material to be pressed, which is conveyed on the endless conveyor. Adjacent conveying elements of the endless conveyor have intermeshing fingers, and the pin connecting the conveying elements penetrates these fingers, such that in the pressing zone the conveying elements assume a pivot position with respect to each other in which the outer side of the endless conveyor forms a closed, plate-like surface without protrusions of recesses. The pressing zone follows a break open zone in the circumferential direction of the endless conveyor, and in the break open zone the endless conveyor is deflected such that the outer side thereof is concavely bent.
