Abstract
A method for the application of an aqueous treatment solution to the surface of a strip which is moving at a preset trip speed, includes the following steps: spraying the aqueous treatment solution onto at least one rotating roll of a roll coater with a rotary sprayer having spray rotors disposed side by side in the longitudinal direction of the roll, to which the aqueous treatment solution is supplied and which are made to rotate by a spray rotor drive so that the treatment solution, driven by the centrifugal force, is sprayed in the form of a spray jet onto the surface of the roll; and applying the aqueous treatment solution to at least one surface of the strip by moving the strip past a rotating application roll of the roll coater, with the application roll transferring the aqueous treatment solution in the form of a wet film onto the surface of the strip. Additionally, related to the method, there are an application device having a roll coater and a rotary sprayer as well as to a system for carrying out the method.
