APPARATUS AND METHOD FOR UV IRRADIATION OF ONE OR MORE RADIATION-CURABLE COATINGS

摘要

The present invention relates to an apparatus for UV irradiation of one or more radiation-curable coatings, which coatings have been applied to a substrate, which apparatus comprises a radiation unit for irradiating said one or more radiation-curable coatings present on the substrate, which substrate is passed under the radiation unit, wherein the apparatus further comprises a shutter element, which shutter element is positioned between the substrate and the radiation unit, and which comprises at least one plate, which plate is movable over some distance in the plane substantially parallel to the substrate for defining the area over which said one or more radiation-curable coatings present on the substrate will be irradiated by the radiation unit.
