Possibility for installation on Fourdrinier that can be later upgraded to Crescent Former

Headbox is supplied with a supplementary frame to enable installation in the Fourdrinier

Installation in two steps

On the first step, only the headbox is installed while existent Fourdrinier is maintained

This step already offers significant gains such as improved web formation and basis weight cross profile

On the second step, Fourdrinier is replaced by one Crescent Former while the headbox is reused and installed in a new position at the top of the new Crescent Former
