Abstract
A double crucible system is disclosed for the production of light conducting fibers. The system has an interior crucible which can be axially displaced in relation to the exterior crucible which is concentric thereto. The spacing of the crucible jets in the exterior and interior crucible in relation to one another is thereby altered so that the proportion of the cross-sections of the fiber core and the fiber casing is continuously altered.
