Headboxes - an overview | ScienceDirect Topics

Originally, the pressure to accelerate the stock to the speed of the paper machine was supplied by a hydrostatic head of liquid. But as Fig. 5.5 shows, high speed paper machines require too much pressure for this to be practical, so paper machines now use closed, pressurized headboxes to supply the necessary pressure. Paper machines operating above 2500 ft/min require a special, high pressure ...
