Glass fiber forming apparatus.

摘要

Glass filaments are ejected from a rotating rotor (3) through orifices (4).
<??> A jet of flame (14) causes formation of secondary filaments suitable for forming e. g. glass wool.
<??>This jet (14) is also used to heat the lower part of the rotor (3), using only the outer zone (13) of the flame.
<??>The upper part of the rotor (3) is heated by an auxiliary burner (15) whose flame (16) extends along the upper wall (6) of the rotor (3).
