This term is often used as a synonym of air-cushioned headbox. |
|
|
|
Notes 2: |
|
The adjective “pressurized” is the American variant of “pressurised”. We have adopted the America spelling, since the British one is rarely used. |
|
|
|
Notes 3: |
|
The pressurized headbox represents an evolution of the open headbox, in which the discharge head is provided solely by a gravity head of stock. This type of headbox is not used for the manufacture of coated papers. |
