WebbRolling Process is a deformation process in which Metal (s) in its semi-finished or finished form is passed between the two opposing rollers, which reduces the metal’s thickness through the compression process. The rollers rolls around the metal as it squeezes in between them. 3. Working Principle of Rolling. The Rolling Process … WebbSoft 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.
