Headbox

 

 
High-pressure (closed) headbox runs with an air cushion and with deflocculation rolls. It is used particularly on paper machines intended for a speed up to 600 m/min. with diverse substances, i.e. with different flow rates and consistencies. The headbox provides uniform distribution of paper stock on a PM longitudinal wire.
 
Hydraulic headbox operates without air cushion and is fully filled with paper stock. It has some elements as classical high pressurized closed headbox. Main difference lays in built-in block with stage diffuser and an installation of pulsation damper in front of the headbox.
