  • Making mineral fibers including adjustment of the position of a stream of glass and a rotor
    Patent number: 6202448
    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).
    Type: Grant
    Filed: August 26, 1999
    Date of Patent: March 20, 2001
    Assignee: Isover Saint Gobain
    Inventors: Alain Melinand, Luc Alliel
