Multicoat: Traditional Roller Infill Machine

Traditional roller infill machine.

The Multicoat roller padder is the latest version of BERGI S.p.A.’s traditional pigmenting machine.
Completely redesigned, the Multicoat is the result of many years of experience in the field of application, which began back in 1985.
In developing this new model, a lot of work has been done to achieve a machine that is simple to use yet highly versatile, to accompany the user in various work processes.
Wide opening of the doctor blade for easier roller cleaning, easily removable washing tank, electric adjustment of the thickness of the working right and left independently, are just some of the technical details that distinguish this machine.
