Abstract:
An apparatus for passing multiple fibers having curable coating thereon through a high intensity curing zone, comprising:a) an irradiator having a curing zone; b) a transparent tube enclosing said curing zone; c) a plurality of coating dies disposed upstream of said irradiator to coat the fibers; d) a plurality of take-up mechanisms disposed downstream of said irradiator to guide the fibers through said tube; and e) said coating dies and said take-up mechanisms are rotatably displaced relative to each other about a longitudinal axis through the centerline of said curing zone so that the fibers at an intermediate location between said coating dies and said take-up mechanisms define a cylindrical volume having a diameter less than the diameter of said tube so that the multiple fibers can pass simultaneously through said tube.
