Abstract

A process for producing products in web form comprising at least two layers, in which a composition emerging from an applicator is applied as a layer to a substrate in web form which is guided on a transport means, said application taking place with application of electrostatic charges, and in which the substrate coated with the composition is electrostatically neutralized before departing the transport means, electrostatic charges being applied to the web-formed substrate prior to coating, by means of a substrate electrode, so that the substrate is pressed onto the transport means.
