Abstract

A continuously operating press includes a press table, a press ram facing the press table, first and second flexible endless steel bands which transfer a pressing pressure to and draw a material to be pressed through an adjustable pressing gap, and driving drums and deflecting drums which drive the first and second endless steel bands around the press table and the press ram, respectively. Rolling bars are disposed with their axes being transverse to the running direction of the steel bands and extending over the entire working area of the press. Heated platens are attached to the press table and press ram, respectively, with the rolling bars rolling on the heated platens. The heated platens have end surfaces which are connected to one another via straight butt joints. The heated platens also have bore holes formed therein which extend parallel to the longitudinal direction of the press and which are independently heatable to provide a plurality of heating surfaces in each of the heated platens. Roll platens at least partially cover the heated platens and extend over the entire working area of the press. The roll platens have a thickness in a range of 7 mm to 23 mm and a Brinell hardness of 250, are heat treated on opposite surfaces, and have a precision ground finish. Finally, expansion joints join the roll platens and extend obliquely relative to the running direction of the steel bands.
