Abstract (en)

Apparatus (100, 200) for photopolymerizing/drying a coating applied to pieces (10) wherein said pieces (10) to be dried are conveyed inside an inert tunnel (30) inside which there is provided a controlled atmosphere having a composition different from the earth atmosphere, said apparatus comprising:- a conveyor of said pieces,- at least a supplying bar (1, 2, 3, 4, 5, 6) for the controlled supply of an inert gas,- said inert tunnel being provided with at least one photopolymerizing/drying lamp (12) for photopolymerizing/drying said coating applied to said pieces (10),characterized in thatat the inlet and/or outlet of said pieces (10) to be dried, said tunnel (30) is provided with at least one device, preferably in the form of a hood (31, 32), suitable for generating an air blade.In a further feature said tunnel (30) is in a fluidic connection with a fixture (40) inside which there is provided said lamp (42), said fixture (40) being isolated from the natural earth atmosphere; said fixture (40) being supplied with the same inert gas provided through said bars (1, 2, 3, 4, 5, 6), which gas reaches the inert tunnel (30) through said fluidic connection in addition and/or alternatively to the inert gas provided by said supplying bars (1, 2, 3, 4, 5, 6).
