Engineering tailored to your calendering application

The correlation of rovalrolls engineering and your calendering application (models below) enables the adaptation of the cover material and filling process to your operating conditions and paper grade (LWC, Coated, SC, speciality paper).

This preliminary engineered design allows rovalrolls to produce  supercalender roll fillings customised to your specific application.

Paper calenders engineered design

The calendering conditions particular to each paper grade are of paramount importance for the cover engineering and the calendering result.
