Paint application problems III: roll and roller coating.

Industrial roll coating and roller coating of architectural and

maintenance coatings are similar processes. Both involve cylindrical

applicators that transfer paint to the surface being painted. Roll

coating is a high speed process for coating metal, wood, or composite

flat stock (coils of metal, sheets of wood, or composite material).

Coiled metal is rapidly uncoiled, painted, baked, and recoiled.

Direct roll coating (also called forward coating) is almost exactly

the same as roller application of architectural paints. The only

difference is that the flat stock moving in the same direction as the

roll on the coater may run at
