Roll Coater Types

 

Direct Roll Coater

This is the basic form of a roll coater and all other designs stem from this. A DRC consists of a support roll, an application roll and a metering roll.

 

 

 

 

Differential DR

A DRC where the Metering roll runs differentially to the application roll, giving a smother finish to the product.

 

 

Reverse Roll Coater

A RRC is basic DRC with a large diameter Drum positioned after the application roll. This runs slower and in REVERSE to product flow. Reverse Coaters are generally used for filling surface defects in the substrate being coated.

 

 

 

Combination Coater

A dual DDRC used where a “wet on wet” application of coatings is required. The second application roll runs at a higher speed in reverse direction applying a very smooth coat.

 

 

 

 

Roll Coaters can be manufactured for products up 12 feet in width and line speeds exceeding 400 feet per minute. Numerous options and customization is available.
