A system and method is disclosed to automatically lift the curtains of the exit hood of a machine for the production of float flat glass by the floating process. A light beam emitter is provided for a light beam which strikes the surface of the glass ribbon, being formed, and is reflected by that surface. A light beam receptor receives the light beam reflected by the surface of the glass ribbon and provides a signal representative of the absence or deviation of the reflected light beam should there be a break in the glass ribbon. A controller receives the signal representative of the absence or deviation of the reflected light beam, and provides operating signals to the actuators of the i) curtain lifting mechanism, ii) reheating system, iii) glass edge follower mechanism and iv) alarm of the glass ribbon forming machine. These signals automatically a) lift the curtains to avoid clogging of the broken glass ribbon, b) operate the reheating system of the exit hood, c) retract the glass edge follower mechanism, and d) trigger the to allow for a rapid restoration of the glass ribbon forming process.
In a glass manufacturing machine for the production of float flat glass as a glass ribbon, which includes an exit hood for the glass ribbon, liftable curtains for the exit hood, and, a system to automatically lift the curtains of the exit hood, comprising:
