ABSTRACT:
A method for producing glass fibers with centrifugal force, comprising melting raw materials for the production of glass fibers in a melting furnace, flowing-down the molten glass from a nozzle at the bottom of the furnace so as to let the molten glass fall onto grooves coated with a glass layer, the grooves being engraved around the total peripheral part of a rotary disc provided below the melting furnace and rotating at a high speed, and simultaneously discharging a combustion gas from a ring burner provided above the inner part of the rotary disc radially to the surroundings of the rotary disc so as to control and maintain the grooves to a prescribed temperature; and an apparatus therefor. The molten glass falling onto the grooves is elongated fibrously by radially spouting the molten glass to the surroundings of the rotary disc with the aid of centrifugal effect due to the rotation of the disc, and thus the production of glass fibers can be done satisfactorily.
