ABSTRACT:
A method for the production of single-material light-guiding fibers which have a core supported in a glass sheath in a cantilever manner by glass webs characterized by providing a crucible having an exit nozzle with an opening having a configuration of the cross section of the light-guiding fiber with a core portion connected by web portions to a surrounding annular portion, providing molten material of the light-guiding fiber in the crucible, drawing the molten material from the crucible through the exit nozzle to form a continuous integral workpiece having a core portion supported in a glass sheath in a cantilever manner by integral glass webs and continuously drawing the integral workpiece into the single-material light-guiding fiber. The crucible is formed by a pair of hollow bodies supported in an outer cylindrical member in a cantilever manner so that the cylindrical member and the pair of hollow bodies form the exit nozzle with the desired configuration.
