Abstract
A production installation for the contact toughening of glass sheets comprises a horizontal furnace for heating the glass sheets, a press containing two liquid-cooled pressing plates, a feed apparatus for transferring the heated glass sheets into the press and a removal apparatus for removing the toughened glass sheets out of the press. To the lower pressing plate, a solids-transmitted sound pick-up is coupled which, if a glass sheet breaks in the press, supplies an electrical signal. From this signal, after suitable processing of the signal, the control device is triggered, and as a result thereof interrupts the process sequence.
