Abstract

The invention relates to apparatus for curing an object by using UV radiation, the object being made, at least in part, of a material that is cross-linkable under UV radiation, said apparatus including: UV radiation sources (2); a tube (3) made of a material that is permeable to UV radiation, the tube being surrounded by the UV radiation sources (2), and being designed to receive at least a portion of the object to be cured; and gas feed means for generating a gas flow (15) through the tube (3) along a general flow axis (9). According to the invention, the apparatus further includes channeling means (4) for causing a portion (16) of the gas flow (15) to constitute a gas screen sweeping the inside sidewall (5) of the tube (3).
