摘要
A system to automatically lift the curtains of the exit hood of a machine for the production of float flat glass by a floating process, comprising: a light beam emitter to provide alight beam inciding on a surface of a glass ribbon to be reflected thereby; a light beam receptor to receive the light bean reflected by the surface of the glass ribbon and providing representative of the absence or deviation of the reflected light beam because of a broken of the glass ribbon; a controller receiving the signal representative of the absence or deviation of the reflected light beam, providing operating signals to the actuators of the curtain lifting mechanism, the reheating system, the glass edge follower mechanism and the alarm of the glass ribbon forming machine, to automatically lift the curtains avoiding clogging of the broken glass ribbon, operating the reheating system of the exit hood, and retract the glass edge follower mechanism, to allow a rapid restoration of the glass ribbon forming process.
