    Patent number: 5229582
    Abstract: A flexible heating element is constructed by securing a flexible layer of conductive material constituting an electric heater to a flexible sheet. The layer of conductive material is connected to an electrical supply means by at least one electrode which has an embossed surface with protuberances that make direct contact with the layer of conductive material. A thermoplastic polymeric based adhesive at the interface between the embossed surface and the conductive layer secures the latter to the electrode.
