ABSTRACT:
The invention relates to a dual-belt press for a continuously advancing web of material comprising a rigid press frame, deflection drums mounted for rotation on bearing bridges of the press frame, upper and lower endless press belts guided over the deflection drums and pressure plates disposed at the rear sides of the press belts for exerting pressure on the web of material. So that the web of material may be simultaneously calendered in such a press, at least those deflection drums provided on the entry side of the press are mounted for movement relative to the pressure plates and are adapted to be tensioned against one another by adjusting means such that the pressure exerted in the gap between these drums (calendering) is preferably greater than and independent of the pressure exerted by the pressure plates.
