A shutter, adapted for use in a system for the radiation curing of a line of articles, includes a number of adjacent baffle units, the blades of which are configured and spaced to substantially prevent the passage of radiation, while permitting the flow of air through the shutter. To minimize the tendency of thermal expansion to distort the shutter, the units are expandably mounted along the length of the supporting frame, and the blades extend transversely thereof.
