ABSTRACT:
An electrical heating element module particularly useful for heating the teeth of a hair comb or pick includes a pair of parallel, side-by-side spaced elongated central conductors having wound thereon a fibrous inorganic electrical insulation material, such as glass yarn, with the opposite ends of each central conductor exposed. An electrical resistance heater wire is wound over the glass insulation yarn on one central conductor and then over the yarn of the other central conductor and making contact with a corresponding end of each central conductor thereby providing effectively one electrical resistance heater. The central conductors are vertically supported by a flat insulator having a pair of sockets provided with spring contacts for establishing electrical connection to the remaining exposed ends of the central conductors. Each insulated central conductor and heater wire thereon is surrounded by a separate tubular non-fibrous insulation sheath, which in turn is enclosed by a separate tubular metallic sheath adapted to form the exterior surface of a comb tooth.
