PrimeRoll Solutions tailored to the papermaker´s needs

The ANDRITZ Küsters PrimeRoll technologies, combined with PrimeCal calenders, are the key to success for state-of-the-art paper and board qualities.

The ANDRITZ Küsters PrimeRoll technologies are combined with all PrimeCal calenders to produce state-of-the-art paper and board qualities. Hard- or soft-covered, deflection-controlled rolls form a uniform nip with the heated roll. The PrimeRoll MHV technology ensures exact CD caliper control over the full width, even at line loads of approximately 5 N/mm. Thus, no external profiling devices are needed.
