Specially designed hydraulic headbox for tissue machines with optimized jet-to-wire ratio.
The hydraulic headbox represents the critical first stage in tissue sheet formation, where fiber suspension is transformed into a uniform jet directed onto the forming fabric. Parason's hydraulic headbox for tissue machines combines five decades of pulp and paper engineering expertise with advanced fluid dynamics design to deliver exceptional stock distribution accuracy.
Our headbox system features an integrated pulsation dampening tank that eliminates pressure fluctuations from the approach flow system, ensuring a stable, consistent jet velocity. The precision-engineered turbulence generator creates controlled micro-turbulence that prevents fiber flocculation and promotes optimal fiber orientation.
With automatic dilution control capability, the Parason hydraulic headbox enables rapid response to process variations and facilitates fast grade changes—minimizing transition waste and maximizing production efficiency.

Advanced technology for superior tissue formation
Integrated air-cushioned dampening tank eliminates pressure variations, delivering stable flow for consistent jet quality.
Precision-machined turbulence tubes create controlled micro-vortices that disperse fiber bundles and prevent reflocculation.
Motorized dilution valves enable real-time CD basis weight profile adjustment with closed-loop scanner feedback.
Converging slice channel design with adjustable lip provides precise control over jet thickness, angle, and velocity.
System design enables transition between tissue grades with minimal adjustment time and reduced off-spec production.
Heavy-duty structural design with precision-machined surfaces ensures long-term dimensional stability.
Streamlined flow path design minimizes hydraulic losses, reducing pump energy consumption by up to 15%.
Gentle stock handling through low-shear flow passages preserves fiber length and bonding potential.
