ABSTRACT:
A continuously working press includes first and second flexible, endless steel belts which are guided around a press table and a press ram via drive drums and return drums and which are supported on a plurality of roller bars. Each of two entry systems has an entry area which extends from an entry tangent to a starting point of a high pressure area and which is divided into a roller bar orientation area, a curved precompression area for the material to be pressed, and a straight compression area. The last third of the roller bar orientation area and all of the precompression area of each of the entry systems have a radius of curvature R.sub.E which is between one and two times the radius of curvature of the return drums R.sub.U. A plurality of computer-controlled hydraulic supporting members support the first and second entry systems and apply a pressure to the material to be pressed. The applied pressure increases constantly from 0 bar at the entry tangent up to a maximum pressure HP.sub.max at the high pressure area. The hydraulic supporting members provide a servo-hydraulically adjustable force profile having a variable compression angle, with the applied pressure increasing constantly from 0 to HP.sub.max /4 from the start of the roller bar orientation area up to the end of the first one quarter of the precompression area.
