PCT No. PCT/CH86/00165 Sec. 371 Date Sep. 21, 1987 Sec. 102(e) Date Sep. 21, 1987 PCT Filed Nov. 27, 1986 PCT Pub. No. WO87/03530 PCT Pub. Date Jun. 18, 1987.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 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). The assembly is then 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). |
