Abstract (en)
[origin: WO2022073862A1] The present invention relates to a curing apparatus (1, 2) for coatings of glass fibers (4) having a receiving space (11, 21) suitable for a coated glass fiber (4) to be passed through in a direction of motion (A), wherein the receiving space (11, 21) comprises a plurality of UV radiation sources (12, 22) which are configured for curing the coating of the glass fiber (4) by means of UV light. The curing apparatus (1, 2) is characterized in that the receiving space (11, 21) comprises at least one protective gas opening (14c, 24c) configured for allowing a protective gas to flow into the receiving space (11, 21), preferably through delivery by the curing apparatus (1, 2), and the receiving space (11, 21) comprises at least one protective gas opening (14c, 24c) configured for allowing the protective gas to escape from the receiving space (11, 21), preferably through suctioning by the curing apparatus (1, 2).
