• Hydraulic performance maintained for the entire production speed range, optimum formation ensured.
• High-performance basis weight profile control by dilution, allowing individual control of orientation and basis weight profile.
• Complete and easy access to the different parts of the headbox in contact with the pulp for cleaning operations which are essential for many specialty grades

1st operational launch on the packaging market

This new S4 hydraulic headbox ALLIMAND is characterized by a highly developped technology, optimized compactness, balance between benefits/investment and its design taking into account the needs of the operators of production. In conclusion, the objectives set for the development of the new ALLIMAND hydraulic headbox S4 have been achieved and the first examples have recently been put into service in the field of packaging.

* The headbox is an element of the paper machine which ensures a uniform distribution of the pulp.
