By means of at least one radiation pyrometer, the radiation emission emerging at the surface of the peripheral wall of a centrifugal ring is continuously detected and used for process control as an actual value in a control circuit for hot gas flow. In consequence, optimum management of the centrifugal ring temperature is achieved and automation of the fibering process made possible, while at the same time harmful over-heating and shock-like temperature changes of the centrifugal ring are avoided.

Method of and apparatus for producing fibers from thermoplastic

A process and apparatus for controlling the operating conditions, particularly the temperature and pressure, of attenuating gas employed in the fiberization of thermoplastic materials. The arrangement disclosed provides for temperature and pressure controls of the hot attenuating gas blast used in connection with a centrifugal or spinner type of technique for making fibers from thermoplastic mineral materials such as glass.
