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, the application taking place with application of electrostatic charges, and in which the substrate coated with the composition is electrostatically neutralized before departing the applicator, the transport means being provided with an electrically insulating coating.

Abstract: A process for continuous production of self-adhesive articles, wherein a) one polyol component is placed in a container A and essentially one isocyanate component is placed in a container B, b) the polyol component and the isocyanate component are mixed in a mixer, c) the polyurethane composition thus mixed is applied to a backing material which is coated with a pressure-sensitive adhesive composition and moves optionally at constant speed, d) the laminate, comprising first backing material, pressure-sensitive adhesive composition and polyurethane composition, is passed through a heat tunnel, for a time which is less than that required for complete curing of the polyurethane, but sufficient for the curves of storage modulus (G?) and loss modulus (G?) of the polyurethane composition, as a function of curing time, to cross each other, e) the laminate is wound up in a winding station.

Abstract: A process for irradiating material in web form by means of electron beams and/or UV rays, wherein the material is applied to a transport means, the material on the transport means is guided through a first irradiation in which the material is irradiated on the open side, the material is transferred from the transport means to a substrate, and the material on the substrate is guided through a second irradiation in which the material is irradiated on the second, hitherto unirradiated, open side.

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.
