<p>Flexible electric surface heating element is for a surface interrupted by an elevation or a recess. The resistor has a recess corresponding to the elevation or recess, and flat metal strips are firmly attached to it as current leads, and run from the recess to one edge and are opposed relative to the recess. Pref. the resistor is a conductive plastics fleece embedded together with the strips, in heat-sealable insulating polyester sheets.</p> |
