Abstract
A radiant heater with partly embedded and otherwise projecting heating coils (16) is produced in that the coils (16) are placed in grooves (14) of a tool or mould (13), the interior of the heating coils is partly filled with a filling material (17) and then the dry, pourable insulating material is pressed thereon. Thus, the filling material forms a counter-die and is removed on taking the compressed insulator (21) out of apparatus (11) in that it drops between the heating coils.
