ABSTRACT:
A flexible tape, adapted to be rolled into a coil and to be cut into sections of any desired length, includes an elongate carrier of woven cloth impregnated with a flexible, carbon-containing resistance layer and a flexible heat shield, coextensive with the carrier, on one side of that layer, this assembly being enveloped in a flat sheath of synthetic resin. A surface of the sheath on the side of the heat shield may be coated with adhesive for detachably securing a backing strip of paper thereto. Two transversely spaced conductors, extending adjacent the longitudinal edges of the tape over the entire length thereof, are in conductive contact with the resistance layer for facilitating the passage of a heating current therethrough. The ends of the conductors in a section cut from the tape can be bared by removing parts of the sheath, the carrier and the heat shield. Several such sections can be laterally juxtaposed for the heating of a larger area.
