Air Cushion Headbox for Paper & Board Machines
An air cushion headbox delivers a uniform stock jet from the approach flow system to the forming section of a paper machine. The headbox integrates the inlet flow channel, turbulence system, air cushion chamber, and slice assembly to control stock flow before it reaches the wire.
VANVEO air cushion headboxes can be configured for different paper and board production requirements. The main design parameters are determined by machine width, operating speed, paper grade, stock consistency, and required flow rate.
Customized Air Cushion Headbox Design
Air cushion headboxes are designed according to the specific requirements of each paper machine rather than using one standard configuration.
VANVEO can configure the headbox according to:
- Machine or wire width
- Design and operating speed
- Paper grade and basis weight
- Stock consistency
- Stock flow rate
- Slice opening and adjustment requirements
- Turbulence system
- Dilution water requirements
- Existing installation dimensions
For replacement and upgrade projects, existing headbox drawings, photographs, and machine data can be used to evaluate the required configuration.
Air Cushion Headbox Applications
VANVEO air cushion headboxes are suitable for a range of paper and board production applications, including:
- Fine and writing paper
- Printing paper
- Kraft paper
- Packaging paper
- Linerboard and fluting
- Paperboard
- Specialty paper
The headbox configuration can be adapted to the required machine speed, paper grade, stock conditions, and forming process.
Key Features
Stable Stock Distribution
The internal flow channels are designed to promote uniform stock distribution across the machine width and stable flow toward the slice.
Controlled Air Cushion
The pressurized air cushion helps maintain stable pressure conditions inside the headbox and supports consistent stock delivery.
Controlled Turbulence
The turbulence system promotes fiber dispersion and helps maintain a uniform stock flow before the jet reaches the forming section.
Precision Slice Adjustment
Manual or automatic slice adjustment can be configured according to machine requirements for controlled jet delivery and cross-directional profile adjustment.
Stainless Steel Construction
Wetted parts can be manufactured from stainless steel selected according to the stock conditions and operating environment.
