C03B37/02736 - 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 Means for supporting, rotating or feeding the tubes, rods, fibres or filaments to be drawn, e.g. fibre draw towers, preform alignment, butt-joining preforms or dummy parts during feeding
