Abstract
At least one radiant heating resistor (10) formed from a corrugated flat material band has in different orientations projections (28) projecting from a corrugated longitudinal edge (14), which on the one hand for retaining purposes engage in an insulation (3) and on the other hand form longitudinal portions (39) with a slightly lower electrical resistance and which for the conventional operating power appear dark compared with the intermediate, visibly glowing longitudinal portions (38). Thus, on putting into operation, there is a very rapidly starting, punctiform lighting up of the corresponding longitudinal portions (38), which then spreads out to a wavy line, as well as a very reliable anchoring of the heating resistor (10).
