ABSTRACT:
The invention relates to a continuously operating press for pressing an advancing web of material, comprising a rigid press frame, an upper and a lower endless press belt, each guided over a pair of deflection rollers mounted for rotation on the press frame, comprising a heating device to heat at least one deflection roller of each pair, comprising a reaction zone located between the upper and lower press belt strands facing each other for pressing the advancing web of material with the simultaneous application of heat, and comprising pressure plates with a heating device at the rear sides of the press belt strands remote from the reaction zone for exerting a pressure on these rear sides and, consequently, on the web of material. In order to attain dimensional accuracy of the laminates exiting from the press, provision is made for the press frame or at least parts of it to be additionally heated by a further heating device and for thermal shield caps which may be moved out of the way to be arranged on the press frame.
