An evolution in response to market productivity requirements

"The new rebuild projects of existing machines require the evolution of paper types, quality improvement or capacity increase," explains Dr Simon CENA, General Manager of ALLIMAND GROUP. "When reconstructing paper machines, priority is given to the most compact equipment which can be installed with minimum auxiliary equipment and enable an optimized balance between the benefits and investment.

A new "high performance" version of the hydraulic headbox

Based on these contextual elements, the ALLIMAND Group has initiated the development of a new S4 version of its hydraulic headbox, with the objective of fulfilling the following criteria:

• ?  Compact design and simplified construction.

• ?  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.
