Our most popular headbox can be used successfully on every grade of paper, board and pulp. The Pro Forma design lets the operator tune flow velocities and turbulence level. The two inside rolls have a wake-free design to allow operation at speeds 50% faster than conventional holey roll headboxes.  Test drive a Pro Forma at the Herty Foundation pilot machine in Savannah, Georgia!

For the world's fastest twin wire machines, Hogenkamp Research has designed a different headbox concept. One which is based on the well known stability of extrusion forming as opposed to the free jet instability inherent with conventional hydraulic headboxes.

Traditionally used on linerboard machines, the secondary headbox is finding new usefulness as a dilution profiling tool where mills do not want to rebuild the primary headbox. It is also an economical means of adding a middle ply of low-cost furnish. For smoothness enhancement the secondary headbox adds a top coat of stock which fills in the valleys of the base ply.

This is the Pro Forma design with an extrusion lip over the a closed forming board. It allows slow running machines to benefit from the special design attributes of the Jetstream headbox above. The main benefit is a wider range of control over md:cd fiber orientation.

Over 2,000 wake-free rolls have been installed worldwide on both new and existing headboxes. The radial tube design creates a wide range of formation enhancing turbulence levels.
