A folding jaw cylinder utilizes folding jaw pairs that automatically adjust the folding gap between the two jaws in each pair in response to the thickness of the folded product. A dual working chamber piston-cylinder unit is placed between first and second rotational carriers of the folding jaw members. One of the chambers is filed with liquid and is linked to a hydraulic accumulator by ways of a flow control valve. The second chamber is provided with compressed air.
