ABSTRACT:
An apparatus is disclosed for providing uniform radiant heat to a substrate by means of a plurality of parallel electroconductive heating wires which are maintained in planar relationship upon heat expansion by means of attachment to a movable bus bar attached to a tensioned spring, positioned in contact with a stationary member which limits its movement to a plane parallel to the plane of the heating wires.
