Abstract
Light weight fabricated metal hot plates in a double backer are initially leveled and maintained flat and coplanar against the forces of thermal distortion by utilizing a dense array of adjustable spring biased support assemblies attached to the underside of the hot plate and securing the plate to an underlying supporting framework. The support assemblies allow horizontal thermal deflection of the hot plate but hold the hot plate heating surfaces firmly against vertical deflection.
