C03B37/02727 - CPC Classification

Classification description:

Manufacture or treatment of flakes, fibres, or filaments from softened glass, minerals, or slags; Manufacture of glass fibres or filaments by drawing or extruding, e.g. direct drawing of molten glass from nozzles; Cooling fins therefor from reheated softened tubes, rods, fibres or filaments, e.g. drawing fibres from preforms; Fibres composed of different sorts of glass, e.g. glass optical fibres; Thermal treatment of the fibre during the drawing process, e.g. cooling Annealing or re-heating
