Filed:

Appl. No.:

6/135808

Inventors:

Philip W. Dalrymple - Doraville GA
Michael J. Hyle - Doraville GA
Daryl L. Myers - Lawrenceville GA
James G. Wright - Roswell GA

Assignee:

Western Electric Company, Inc. - New York NY

International Classification:

B65H 5402
B65H 6704

US Classification:

242 18A

Abstract:

In taking up drawn lightguide fiber (31), the fiber is distributed on the hub of one of two coaxially mounted takeup spools 42-42 which are driven independently of each other at ends of indexable turrets (94-94) that also have spools mounted on their opposite ends. Following takeup on one of the spools, a distributor 201 effects a cutover to a collector groove of the adjacent spool until several convolutions of the fiber are secured within the collector groove to provide access to a leading end of the fiber on this spool for testing purposes. Then the distributor begins its traverse across the hub of the empty spool and the lightguide fiber which extends across the adjacent collector spools is severed to form an end portion on the spool now being filled, said end portion advantageously being accessible for testing. The full spool is caused to be moved out of its takeup position and another empty spool is moved into that position to be filled after takeup has been completed on the spool in the other takeup position.

Abstract:

An induction furnace (60) for reflowing a portion of an optical preform (12) in order to draw a lightguide fiber (11) therefrom includes a tubular susceptor (80) which is disposed centrally within a beaker (75) and a sleeve (82) which is disposed concentrically about the susceptor. The sleeve is spaced from the susceptor and is surrounded by insulating grain (83). A high frequency coil (84) is energized to couple its electromagnetic field to the susceptor to heat and reflow a portion of the preform. The movement of contaminating particles of the insulating grain into the interior of the susceptor is prevented substantially by annular, felt-like discs (91, 105) at the bottom and top of the beaker. The discs collect particulates which move downwardly and upwardly and because of their compliant engagement with the beaker and with the sleeve, they provide seals at those interfaces. The discs also are effective to prevent inadvertent lateral movement of the sleeve to maintain the concentricity of the sleeve and the susceptor.
