METHOD AND DEVICE TO APPLY COATING TO MOVING METAL STRIP Russian patent published in 2006 - IPC B05D7/14 

FIELD: processes adapted for applying liquids or other fluent materials to particular surfaces, particularly to metal surfaces, for instance to car bodies.

SUBSTANCE: method involves bringing coating material into contact with moving flexible metal strip and choosing temperature of metal strip to be treated to provide good adherence between coating material and metal strip during pressure application operation. Method also includes advancing flexible metal support strip along straight path section of strip to be treated with uniform speed; moving the coating material along the metal support strip until the coating material takes its position between the support strip and strip to be treated; locally applying pressure to the support strip and to the metal strip to be treated along above path, wherein means for pressing force equalizing across the support strip is installed in point of pressure application.

EFFECT: elimination of air-bladders forming in coating applied on metal strip due to prevention of direct contact between pressure application means and the coating material.
