Dubois S Series Differential Roll Coater
The Dubois S Series Differential Roll Coater provides a precise application of coating to flat substrate in a newly upgraded machine which is sized as a direct replacement for many competitors machines. The differential roll coater uses a rubber application roller to apply coating directly to a part passing through the machine; the durometer of these rolls is selected based on the finish being applied. The coating thickness is varied by the doctor roll pressing against the applicator roll which uses variable speed and direction capabilities to apply coatings with precise control of film thickness. The air loaded doctor roll assembly combined with Dubois' unique pivoted roll arrangement allows for easy changeover of materials.

•Variable speed rubber covered applicator roll
