Engraved Roller System

Function/Description

In case of the engraved roller system, also called kiss coating system, the carrier material is led through between two rollers. From a dipping basin, the application roller passes the paste onto the substrate. The coating paste quantity is determined by the design or the raster of the applicating roller.

The surplus paste on the applicating roller is scraped off by a knife. A a lacquering unit can be integrated directly into the coating machine or as a separate coating system. Coating layers of between 2 and 10 µm can be applicated by the lacquering process.

In most cases, acrylic or PU- varnishes are applicated. The application of e.g thin varnish layers onto already coated material is mostly being done with engraved roller systems.
