Our headbox consists of a manifold distributor, flow stabilization elements and slice, will distribute the papermaking stock uniformly across the width of the wire section. The papermaking stock pumped in a pipe is converted to a uniform rectangular flow with absolutely the same flow rate and flow direction across the wire width.

The air cushion provides a dampening effect on pressure fluctuations in the stock flow entering the headbox. The jet speed leaving the headbox is determined entirely from the height of the free surface inside the headbox. Usually around 10 inches of head on machines running at 500 m/min.

The hydraulic headbox is available with or without a stabilization chamber, which consists of a tube bank and is present between the chamber and the slice. This tube bank is also known as turbulence generator although its main function is to improve the velocity profile in the cross direction.
