Abstract
A lightguide fiber (21) which has been drawn from a preform in a furnace (26) and which has a relatively high temperature is cooled prior to its movement through an apparatus (41) which applies a coating to its outer surface. The fiber is cooled by moving it through a liquid material (42) in a reservoir (40) which is interposed between the furnace and the coating apparatus. The liquid material in the reservoir (40) is the same as the coating material contained in the apparatus that is used subsequently to coat the fiber.
