US Patent 7716953 Method and assembly for fiberizing molten glass

Apparatus and methods for making a continuous fiber product by gathering a plurality of fibers into a strand in contact with a pad wheel that is driven with a low voltage, variable speed motor or drive, and controlling the RPM of the motor in response to a breakout detector. Other embodiments further include accelerating the RPM of the motor and pad wheel at a desired ramp-up rate following the resumption of desired fiberization.
