ULTRAVIOLET CURING APPARATUS FOR CONTINUOUS MATERIAL

WIPO Patent Application WO/2010/039945

A3

An ultraviolet radiation curing system (10) is disclosed for treating a substrate (26), such as fiber optic cable or silicone tubing. The system (10) comprises a processing chamber (12) allowing transport of a continuous piece of substrate (26) to be treated. As the substrate (26) moves through the processing chamber (12), ultraviolet radiation from a plasma lamp (34) activated by a microwave generator (36) treats the surface of the substrate (26). The system (10) comprises two elliptical reflectors (42, 46) of different sizes so that larger diameter substrates may be efficiently treated with ultraviolet radiation. The system (10) may also comprise an ultraviolet-transmissive conduit (54) enclosing the substrate (26) and split into a first portion (84) and a second portion (86), where the second portion (86) is movable from the first portion (84) to open the conduit (54) and allow insertion or alignment of the substrate (26) within the conduit (54) and processing chamber (12).
