ABSTRACT:
A contact heater mounting assembly includes a single rolled flexible sheet which both supports a plurality of heating elements and provides protection for a high cohesion level adhesive on the elements. The assembly thus provides for convenient installation of the elements to a vehicular window glass or other surface to be heated without the need for removal of a separate cover member otherwise utilized for protection of the high level adhesive. In a preferred embodiment, the contact heater mounting assembly is elongate and capable of being rolled into a coiled form. The flexible sheet defines opposed top and bottom surfaces, the top surface carrying a low cohesion level adhesive for supporting a plurality of heating elements, each of which carries a high level adhesive thereon. A plurality of spacers are disposed in pairs, one on either side of each heating element for insuring a gap or spacing between the bottom surface of the sheet and the high level adhesive on each element when said assembly is in coiled form.
