发明名称 METHOD FOR FABRICATING A HEATING ELEMENT
摘要 In order to form a heating element, a coil-shaped hollow path, cut into a plate (10), is filled with an exothermally reacting pulverulent mixture and is compressed by means of a correspondingly shaped pusher (13), a platen being then applied to the upper face of the plate (10). Thereafter, the coil (2) comprised of compressed of reactive mixture is lifted above the plate (10) and covered with a refractory powder to which a binder has been added and the assembly is then compressed by means of a piston (36; Fig. 6). Then, the assembly is placed into a metal container (5) intended to diffuse the heat for heating for example foodstuffs, after the reactive mixture has been ignited through the opening (22).
