The extrusion coating fixture comprises a guide rod, a carriage movably mounted on the guide rod, and a coating head including an opening for directing a curable coating composition to a filament positioned in a channel formed in the coating head. A radiation source is aligned to the coating head for radiation curing of the curable coating composition applied to the filament. Both the coating head and the radiation source are joined to the carriage to move relative to a portion of a filament during application of curable coating composition to its surface.
