2-Sided Adhesive Roller Coater

Adhesive Roller Coater - Union Tool 18453

An adhesive roller coater designed for applying a precise coating of resin adhesive to both sides of the substrate in one operation.

In the Model A Double Coater Roll Configuration, the liquid coating is held in the troughs between the coating rolls and their companion doctor rolls, top and bottom.


Depending on your industry, you may call this a roller coater, a roll coater, an adhesive spreader, an adhesive roll coater, a glue coater, a glue spreader, a two-sided adhesive coater, a two-sided roll coater, or a double-sided roller coater.

Operational Description

The Union Adhesive Roller Coater applies a controlled amount of resin adhesive to both sides of clutch and brake facing plates in a single pass. The 36" work area allows several rows of plates to be fed across the width of the coater simultaneously. A recirculating pumping system automatically pumps resin up to each coating assembly. Removable conveyors on both the front and back of the coating assemblies provide quick and easy adhesive cleanup.
