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

Making mineral fibers including adjustment of the position of a stream of glass and a rotor

A ventilation duct includes an envelope lined on the inside by insulation panels. The panels have a lining on the side of the flow channel of the duct and on at least one part of at least one of transverse edges of the duct. This lining extends over at least one part of each of both sides of the edge and is integrated with the panel. Z shaped sections may be used to hold adjacent panels.

Ventilation duct and insulation panel used for its internal lining

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).
