Abstract

A method for at least one-sided coating of a material web with an application medium is performed by a two-element applicator device having at least one applicator roll and a counter element defining a gap through which the material web is conveyed. The method includes the steps of pre-metering the application medium onto the applicator roll and transferring the application medium onto the material web in the gap. Pre-metering of the application medium to the applicator device is performed by at least one free jet.
