Abstract

A method of producing a coating of solvent-free pressure-sensitive adhesive systems on substrates, especially release-coated substrates, in which a fluid film is applied to a rotating roller by means of a fluid applicator, the pressure-sensitive adhesive system is applied in one or more layers to the fluid film by means of an adhesive applicator, and the roller is contacted with the substrate, so that the pressure-sensitive adhesive system is transferred from the roller to the substrate.
