Abstract
A jet coating method for applying coating mix onto a moving web in a noncontacting manner in ambient pressure which includes the step of directing a jet of the coating mix counter to an approach direction of the web at a velocity sufficiently high to attain a splitting of the jet into a return flow and a coating mix application flow.
Claims4
A jet coating method for applying coating mix onto a moving web (14) in a noncontacting manner at ambient pressure without using a pressurized chamber in a region where the coating mix contacts the web, comprising the step of directing a jet of the coating mix counter to an approach direction of the web (14) at a velocity sufficiently high to attain a splitting of the jet into a return flow (16) and a coating mix application flow (17), said jet being unrestricted in the region where the coating mix contacts the web.
