A process and apparatus for controlling the manufacture of mineral fibers, in particular glass fibers, by use of a fiber-drawing process using internal centrifuging in a centrifuger. The peripheral strip is pierced by a large number of outlet orifices and the radiation emitted superficially by the peripheral strip is measured in order to determine the temperature of points of the peripheral strip and the vertical coordinate of each of the points measured.
