Continuous working press for wood or plastic based panel production has modular pressing frames acting with alternating long and short spacing of supporting points onto press platens

摘要

The press has moving upper(3) and fixed lower(2) columns acting on press platens(18,19) along the press length and comprising frames(21) with ribbed or frame plates. Piston and cylinder units(17) acting on the press platens vary the press gap through which endless steel belts pass. In the press calibrating zone support or bending lines(m) for the lower press platen(18) are offset relative to support lines(n) for the moving press platen(19).
