Date Jun. 6, 1996Man made vitreous fibers are made using a cascade of rotors (4, 5, 6, 7) from melt poured onto the top rotor (4) wherein the melt has a low viscosity (not more than 18 poise) at 1400 DEG C. and has a viscosity of not more than 10 poise on the top rotor (4), the top rotor has an acceleration field of at least 30 km/sec2, and the second rotor (5) is arranged with its center on a line with the center of rotor (4) which makes an angle C of 0-20 DEG and has an acceleration field of 50 to 150% of the field of the rotor (4), and the subsequent rotors (6, 7) have an acceleration field of 120 to 250% of the acceleration field of the rotor (4).
