Method for making a heatable laminated glass containing metallic wires in the interlayer

摘要

For making an electrically heatable laminated glass pane, on the thermoplastic film (1) bonding the individual glass panes to each other heating wires are laid down and fixed on the film (1) continuously from one film edge (6) to the opposite film edge. The heating wires (4) are connected in parallel connection to busbars (3), which are arranged at a distance (A) from the edge (6) of the film (1). Directly next to the busbars (3), the sections of the wires (4) lying between the busbars (3) and the edge (6) of the film are severed by bringing into contact with the wires (4) two electrodes (8, 9) connected to a power source. The electric power causes the wires (4) to be heated to their melting temperature and interrupted between the electrodes (8, 9).
