Abstract
A heater on metal composite unit. A strip of metal has a stripe of an electrically insulative and thermally conductive synthetic resin material bonded to one surface along the length thereof. At least one stripe of an electrically conductive material, having a width less than the width of the insulative stripe, is bonded to the surface of the insulative stripe along the length thereof. A strip of electrical resistance material at least partially overlies the stripes of both the conductive and insulative materials thereby providing a path of electrical resistance material from the conductive stripe transversely across a portion of the width of the insulative stripe whereby when electrical current flows through the electrical resistance material it will supply heat to the metal strip. Apparatus and a process for fabricating these composite units are also disclosed.
