VORRICHTUNG ZUM ZIEHEN EINES BUENDELS VON KERN-MANTEL-LICHTLEITFASERN

A device for drawing a plurality of cladded light conducting fibers utilizing a double crucible having an inner crucible and an outer crucible with each of the crucibles having a bottom and receiving a melt of the respective material, and having nozzle pairs with the nozzle of the inner crucible being aligned axially with the nozzle of the outer crucible, the device including a device for gathering the pulled fibers to form a bundle and for coating the pulled cladded fibers characterized by the nozzles being exclusively arranged at points on the bottoms of their respective crucibles where the same temperature prevails for the glass melt present in the double crucibles. To accomplish this, the nozzles are located between and equal distance from the parallel boundary lines of the bottom of the inner crucible so that the melt drawn through the nozzle travels the same distance in all directions. The device for gathering is a coating cuvette, which is preferably formed of two longitudinal halves which can be moved transversely to the direction of movement of the fibers to facilitate threading the fibers into the cuvette.
