Abstract: An electrically heated composite glass sheet including heating element wires deposited and fixed in place on the thermoplastic film connecting the individual glass sheets together so as to extend from the one film edge as far as the opposite film edge. The heating wires are connected in parallel with buses, which are arranged at a predetermined distance from the edge of the film. Directly adjacent to the buses, the sections of the wires which are arranged between the buses and the edge of the film are severed by moving two electrodes, which are connected with a power supply, into contact with the wires. The electric current heats the wires between the electrodes to their fusion temperature and thereby severs the wires.
