The invention relates to a unit (1) for processing hollow-body plastic blanks (2). Said unit includes a chamber (6) wherein the blanks (2) move along a predetermined path. Said chamber (6) is defined, on both sides of the path, by two side walls (3, 4) having inner surfaces (5) that face each other. Said chamber (6) includes a main section (9) wherein at least one of the walls (3, 4) is provided with a plurality of electromagnetic radiation sources (10). The side walls (3, 4) define therebetween, on at least one end of the chamber, an opening (8) for the preforms to pass therethrough. The chamber (6) includes at least one optical confinement section (12) that extends between the main section (9) and the opening (8) and wherein the inner surfaces (5) of the side walls (3, 4) are optically reflective and converge toward the opening (8). |
