ABSTRACT:
The production of mineral fibers by centrifuging on rollers (3, 4, 5, 6) with horizontal axes from a stream (1) of molten material includes determining the relative position of the stream (1) of molten material in relation to the first roller (3), and controlling this position by use of CCD cameras (8, 11, 40). A camera (11) observes the periphery of a fiber-drawing roller (4).
