Method for designing a reflector for a cassette emitting ultraviolet radiation for the purpose of limiting the shadow cast on a product passing by under the cassette and coating of a product to be polymerised under the action of the said ultraviolet radiation, the said product being held by clamps, characterised in that the point of the edge of the reflector (2) upstream with respect to the direction of filing past, is such that the slope at the last optic ray tangential with the emitter (4) corresponds to the maximum slope of the edge of the clamp (6). <IMAGE>
