Soft nip calendering

The ANDRITZ PrimeCal Soft enables reliable soft calendering for a wide range of applications. It is based on the proven Mat-On-Line technology. The soft calendering process utilizes rolls with a soft, elastic cover that form a nip replicating the surface of the tempered roll with a hard surface – thus improving the paper properties. The finish in general enhances the performance characteristics and printability of the web.

Hard nip calendering

The PrimeCal Hard calender is well suited for precalendering and final calendering of all paper and board grades. It provides a consistent CD caliper profile, bulk control, and excellent surface finish.
